Fixin’ Mistakes

I love that establishing shot as winter becomes spring in the first film. I didn’t attempt to exactly match the angle and lighting, but it’s pretty close. Fiddle with the slider to show what the POA castle (right) would have looked like from the same angle!

Anyway, my main purpose with today’s short post is to clean up some messes! I was alerted to an apparent error in the last post: the front walkway through the arch doesn’t seem to have connected to the walkway around the Chamber of Reception, after all. The truth is far stranger and less certain…but if I’m interpreting the bits of available reference material correctly, there was actually a staircase that led down below the Chamber of Reception, probably entering through a gap in the rocky hillside that supports the CoR. This is my best attempt at reconstructing it:

I was then alerted to another error – there were windows on the hospital wing where there shouldn’t have been. And I discovered an extra chimney in the SS version of the quad, too. So here’s a new SS/POA comparison slider that fixes these issues:

Moral of the story for me: Always double-check all your reference images!

Moral of the story for you: If you think you see a mistake in my work, please do let me know in the comments! I want to get this right and I appreciate the help!

Finishing the SS and POA Quads (and Hospital Wing)

Relatively short post – time to add the cloisters to the original quad. It is very difficult to make out any detail in the single shot of these cloisters in Chamber of Secrets, but it seems very safe to assume that these were based on the cloisters at Gloucester Cathedral. So what the heck, I’m going for it:

The floor is so plain! I mean, the floor looked a lot like that in the later iterations of the quad, but in the beginning, there were footpaths and a fountain and everything. Looks much better with those in place, even if the walls were tall enough to keep it pretty dark in there a lot of the time.

Fun fact: I haven’t built any doorways from the cloisters into the middle there. There would certainly be at least one in real life, and I’d imagine the miniature had at least one, but I’ve got no idea where it would have been, so I’m not going to bother.

Here’s are a couple of views of the complete original quad:

Not my finest texture work, admittedly. Most of what I’ve created for this project holds up a lot better at larger distances.

Of course, this project is all about the changes to the design of Hogwarts. So when did the quad start to change? Well, the hospital wing got added in Prisoner of Azkaban. I strongly suspect (though I’m not absolutely 100% certain) that the raised, cloister-less floor didn’t come till Goblet of Fire. Here are a couple of comparisons between the pre-Azkaban version (left) and the Azkaban version (right), showing the addition of the hospital wing [EDIT: there are too many windows here – see the next post for the fixed version]:

The off-center placement of the hospital wing is intentional, by the way. It was really designed and built like that.

If you’re still having trouble getting a sense for how the different levels line up, here’s an orthographic cross-section:

Should be quite close, if not precise down to the inch. That’s the back terrace on the lower left and the quad itself in the middle.

Next, tackling the walkways out in front of the quad building, connecting up with the viaduct [EDIT: Actually, I’m pretty sure this is not accurate either; again, see the next post for the fix]:

That render could be of any of the first three films, by the way, since that area didn’t change at all (as far as I can tell).

Where do we go from here? The last remaining major castle structure is the lower walkway (around the bottom right corner of that render) and the terrace to which it likely led in the first two films. But it would be an understatement to say that I’m having trouble finding good reference for that area. Still not sure what I’m going to do about that.

One thing I am sure of? It’s been way too long since we’ve done a nighttime render! Like, waaaaaay too long. Almost a year. The model was half its current size! Here are a few nighttime shots of the Azkaban version to help rectify the situation. See you next time!

Transfiguration Classroom

In the early Potter films, scenes in Professor McGonagall’s Transfiguration classroom were shot on location in the chapter house at Durham Cathedral. As part of their efforts to make the original exterior miniature somewhat consistent with the location shoots, Stuart Craig and his team adapted the exterior of the chapter house as part of their design.

I say “adapted” because the details don’t really match. Still, it’s very clear that this structure just south of the middle courtyard (also adapted from Durham) was intended to be the exterior of the classroom.

Here’s the basic shape of the structure:

My “reference board” for this structure is one of my smallest. This is partly because it only existed for two films and partly because it’s not that big or complex a structure…but it’s also partly because reference is really, really scarce. Like…a couple of shots in Chamber of Secrets and a behind-the-scenes photo from Sorcerer’s Stone, plus the floor plan that sits beneath the model. Still, it’s enough to reconstruct what most of it looked like…

…except I have literally zero shots of the far side of the structure, the one facing the courtyard. I’d be in heaven if I could find a shot of the original miniature from an angle like this:

It would clear up my questions about the side of the Transfiguration classroom facing the courtyard, not to mention the original training grounds tower roof on the right. Again…maybe someday. In the meantime, I’m leaving the wall facing the courtyard blank.

Anyway, here’s the less mysterious side with all the nice details:

And, as promised last time, here’s a slider comparing the whole area in the first film (left) to the redesign in the third film (right), including the relocation of the suspension bridge:

Next up…dare I try to tackle the original quad?

Suspension Bridge & Gryffindor Girls’ Tower

When we last saw the Hogwarts suspension bridge in my project, it was an untextured but fairly complete bridge to nowhere. Then, a few posts later, I said that I’d hidden the bridge so I could do some reworking, and that it would return “eventually.” I didn’t really expect that “eventually” would mean two years and a pandemic later, but there ya go.

In the intervening time, I discovered some issues with my original recreation of the bridge, so I just rebuilt it from scratch. The suspension bridge moved in Prisoner of Azkaban; I decided to start with that version, as I did two years ago.

I found that the two ends of the bridge weren’t quite lining up, but that problem went away with some slight cheating.

One challenge is that our only truly close-up view of this bridge in the films is during the dragon chase in Goblet of Fire…but that shot features a different design, and I’ve chosen to ignore it.

Adding the details, and hiding the buildings to the north so we can get a better angle (and let some more light in):

I suppose it’s only fair to also include a reverse angle, this time hiding the south block (and rotating the sky/sun 180°):

But of course, as I said, this is not where the suspension bridge started out. Originally, it was closer to Gryffindor Tower and lower down – in fact, you can see the small building it originally led to on the far left side of the render above.

Back on the opposite (south) side of the ravine, the tower containing the Gryffindor girls’ dormitories originally stood directly above the other side of the bridge. (Not going to dig into the design choice to deprive the girls’ tower of a spire or any discernable windows…) That tower disappeared completely when the suspension bridge moved in Prisoner of Azkaban, although the Gryffindor common room set still hints at its existence.

Again, it’s easiest to see this with half of the castle missing. Drag the slider to compare Sorcerer’s Stone (left) to Azkaban (right):

I should say that I am NOT confident in the accuracy or completeness of the lower left area of the wall in the Sorcerer’s Stone version. The floor plan seems to indicate some sort of terrace or balcony; if it was actually built, I’d imagine it was similar to the one on the right side of the render, in appearance and height. Sadly, I simply cannot find any reference for this area of the original model, so for the time being, I’m just building the main wall itself. Someday, man…someday.

I’d like to show you a similar slider facing the opposite direction, but I think that’ll be more fun and more informative once I’ve built the Transfiguration classroom (AKA Durham Cathedral chapter house). That’s next up on my to-do list…stay tuned for more updates! In the meantime, I’ll leave you with a more familiar Sorcerer’s Stone angle of the suspension bridge area:

And hey, why not – just as a fun bonus, here’s an overhead shot, but with the SS and POA versions both visible and intersecting nonsensically. I’m including the mist pass too because it just looks frickin’ cool.

Wrapping Up the SS Training Grounds

For Sorcerer’s Stone only, the Quidditch training grounds were surrounded by curtain walls, retaining walls, and small towers that were slight adaptations of structures at Alnwick Castle. As we’ve seen in previous posts, a big chunk was redesigned in Chamber of Secrets, and then a big hill covered up the remainder of the original design starting in Prisoner of Azkaban. (The all-digital version in Deathly Hallows and Fantastic Beasts doesn’t have any walls back there at all.)

Because of all this, there’s not a huge amount of reference available for this area of the miniature. It’s certainly easy to find reference for the real thing at Alnwick, but what reference I do have makes it clear that the details don’t always match up. Just gotta do my very best!

I continued around to the far side, where the information is most limited. I’ll compensate for my less-than-complete confidence in certain details here by including the “mist pass” for this render, just for fun. This is a component of the render that’s used to add some atmospheric perspective. The further something is from the camera, the lighter it is, simulating greater amounts of haze between the viewer and the object. Looks kinda cool all by itself, eh?

There’s a low wall that divides the Alnwick Castle lawns in real life, and it shows up in the blueprints for the first Hogwarts miniature as well. The real thing even shows up in a single (edited) establishing shot of the location, at the beginning of the flying lesson. But I’ve never found a single photo of that spot in the miniature, which makes it tough to know exactly how much detail they put into it.

I’m cheating with all these lawns – they’re just textured surfaces with no actual blades of grass. To create those would require particle systems or geometry nodes or something, and I don’t think my computer could handle the amount of grass that’ll eventually be part of the model. Even filling just this area with actual blades of grass would be pushing my luck:

So I’m not really sure how I’m going to handle the landscape as a whole. The goal is to have it look…well, not like this render I created as a kid in Bryce 3D, circa 1999:

I can tell already that I won’t be able to rely solely on procedural materials. At the very least, I may need to hand-paint some changes in coloration near the footpaths and whatnot. Perhaps another day. In the meantime, we’ll close out for now with an extremely wide (and slightly distorted) angle reminiscent of the first shot of the training grounds in the first film.

…and the “Sorcerer’s Stone” Training Grounds Tower!

We’re gonna start today’s post with the good stuff: before-and-after sliders comparing the COS-through-OOTP training grounds tower I finished last time to the original training grounds tower! (I’ll show you the process of creating the latter afterward.)

For each slider below, the SS version of the tower is on the left and the COS-OOTP version is on the right. Notice how little the lower areas of the structure change, and how much the upper areas of the structure change!

Before I built this original version, I realized that I didn’t have the adjacent areas built in the SS model, which would make it look kinda funky. So I first took care of some housekeeping: duplicating stuff from the POA model to the SS model, creating new collections (folders) for different structures, etc.

The Defense Against the Dark Arts tower moved in Prisoner of Azkaban, so I created a copy of it and moved it to its original position. I also removed some asymmetry from the Durham wing that was introduced in Azkaban to make room for the Dark Tower:

God, I get so nostalgic for those candle snuffer roofs on the Durham wing from the first couple films.

Anyway, as you’ve seen with the sliders, the lower areas of the COS-OOTP training grounds tower are identical to the original design from SS; they just redesigned most of the upper areas. So I brought a copy of that training grounds tower into the SS model and started ripping off all the top parts that were different. Here’s a fun render partway through that messy process:

Ugly, innit? Well, if you want to make an omelette, you’ve got to crack some eggs.

There, now the metaphorical eggs are beginning to set! Nearly done:

The roof is tricky because in addition to the gable, there seem to be some flat areas, but I don’t have any good shots from above. This is another area where my ideal levels of accuracy and precision simply aren’t going to be possible, unless some kind soul manages to send me reference photos or technical drawings of this spot that hasn’t been part of the miniature for almost 20 years now.

This seems to be the best inference possible from the available information:

Its central courtyard is particularly mysterious. It corresponds to a space at Alnwick Castle that was used in a brief scene in the first film, but the shape is so different in the miniature that it’s impossible to know what sorts of architectural details were in there. In the video game, the courtyard is omitted altogether, continuing the flat roof over the entire thing; you can see it at 3:07:02 in this video. But that castle has numerous other inaccuracies, so I take it with a grain of salt.

One of the things that’s starting to stick out for me is the lack of flashing on all my roofs. It definitely hurts the realism. I’m going to need to fix that at some point.

Anyway, here’s one last shot of the finished tower! Next, I’ll probably finish up the SS-era curtain walls. See you next time!

Virtual Tour Video & Barbican/Gatehouse

Have you subscribed to my YouTube channel? If so, you’ve probably already seen that I posted a new work-in-progress virtual tour of my Prisoner of Azkaban Hogwarts model last week. If you haven’t subscribed yet…get on that! I’m not currently posting a lot of videos, but subscribing will make sure you know when I do.

But that’s not our main focus for today. Today we’re going to be continuing with progress after that video, building the structure from the first two films that corresponds to the gatehouse and barbican at Alnwick Castle.

As I’ve mentioned before, the filming miniature and the real location don’t always match up perfectly. I’m aiming more for the miniature, but it’s a lot easier to find reference for the real thing, so I’m having to rely on that to fill in the gaps. Here, I’ve got the basic structure of just the gatehouse built:

(This is where Neville zooms upward again on his broom before nearly impaling himself on a statue’s spear.)

Next come details on the façade facing the training grounds – windows, arrowslits, lanterns, and of course the classic Hogwarts-style torches that were added as temporary set dressing for the film shoot. The one on the right is the one that Neville’s robes catch on, slowing his fall a bit:

Note that this is a view you couldn’t have seen in any of the movies – it simultaneously shows the gatehouse (from the first two films) and the clock tower (from all but the first two films). If you looked at this angle during SS or COS, there’d be no castle visible in the background, and if you looked at this angle from POA onward…well, you’d be underground.

I should also mention that I have zero good shots of this side of the structure in the miniature, so here I’m going purely off of the real thing. Same goes for that small tower toward the left, which I haven’t detailed yet in the above render. Let’s rectify that, and add the similar tower on the other side of the gatehouse:

The flying and Quidditch lessons in Sorcerer’s Stone were both shot on location here, and these towers are seen pretty clearly, so I have no reservations about mimicking the real thing without knowing what they looked like in the miniature.

If this doesn’t look…right, it may be because Alnwick Castle is lighter, yellower, and more contrasty than the miniature. But I’m just using my main castle texture, which is based off of the most neutrally-lit photos of the miniature I’ve found. Also, this area is in direct sunlight in the film, not the shade. Plus, you know, the ground is still missing.

Anyway, on the outside of the gatehouse, let’s start adding the barbican. At the real Alnwick Castle, this was added to the gatehouse around the 14th or 15th century, greatly enhancing the castle’s defenses. I’ve had trouble finding reference for a few spots along the battlements, but this old 3D digital survey I found was helpful.

These areas in my model have really become a hybrid between the miniature and the real location:

Not too shabby! I wouldn’t want someone throwing boiling water on me from those battlements.

The part of this structure that was tweaked the most for the miniature was the entrance of the barbican. In the real world, the area outside the archway appears to be a paved semicircle, a small car park, and then the street. In centuries past, this would have been the only entrance to the grounds – basically just a really beefed-up, defensible drawbridge. But at Hogwarts, this isn’t an entrance at all. The terrain drops off pretty steeply, and so the area outside the archway is just a small terrace with no apparent purpose beyond being a lookout point. (They also swapped out the Percy lion heraldry over the archway for the Hogwarts crest, but that’s barely visible.)

If none of that is sounding familiar, it’s because it’s only seen indistinctly from great distances, and only on rare occasions, and only in the first two films, and only from the side. But blueprints and behind-the-scenes photos provide just enough insight to allow us to simulate cool new views like this:

It might look slightly more familiar from the side:

Any better? You could be forgiven for still not recognizing it. This is about the best view of the barbican exterior we ever get in the movies:

And you can’t even see the gatehouse there! So…yeah, not Hogwarts’s most distinctive feature. Still, it’s good to have it complete! Well…complete with the exception of the statues that stand on top of the ramparts. But those are full-on human figures, and I haven’t yet decided whether to sculpt them from scratch, adapt them from free models posted online, or omit them altogether.

Maybe I’ll have an answer in the next post. In the meantime, have a great weekend! Or week, or whatever, since clearly I don’t control when you’re going to be reading this.

Continuing the Curtain Walls

Relatively short post today. We’ll start off with some orthographic views of the POA model, by request. This is the state of the model before the progress you’ll see later in this post.

I always enjoy these blueprint-style perspective-less views.

Anyway, onward to today’s update. Let’s start fleshing out the remaining walls surrounding the training grounds! I’m kinda doing the COS version, since most of this is covered by a new hillside from POA onward, but that’s okay.

I hadn’t touched this area since late March 2019…crazy to think that it’s now been over 2 years since I started this whole project!

There’s not a lot of reference for this area of the miniature, but I have found some shots. Between those and photos of the real thing at Alnwick Castle, I think my results are pretty accurate. Interestingly, that guerite (small lookout tower) closest to the camera seems to have been slightly redesigned partway through the construction of the model. I’ve gone with the final design that was glimpsed – if only barely – in the films.

The next structure along the walls is Alnwick Castle’s barbican and gatehouse. (This is the building from which Neville falls and breaks his wrist in the first film.) I had already done a bit of work on this structure as part of an early attempt at recreating Alnwick itself – here’s an old render from this post:

I built this to the same scale as the main Hogwarts model, so it was easy enough to drop that into place and add brick textures:

As we’ve seen with other areas, I’ve built the walls so they go quite a ways down. From this view inside the training grounds, the lowest parts will eventually be covered up by grassy lawns. But on the outside, the terrain is rocky and uneven, and in some areas it slopes downward to reveal the lower areas of the wall. It’s easiest to just make the walls really deep and then cover a lot of it up with the terrain later on.

Fortunately, there are some nice orthographic drawings of the barbican/gatehouse structure on a placard at the location. These provide some very helpful reference. As always, my goal is to capture at least one of these, in roughly descending order of importance:

  1. The onscreen appearance and imagined reality of the castle in the films (which is achieved through a mixture of location shoots, miniatures, CGI, etc.)
  2. The main 1:24 scale VFX miniature of the whole castle
  3. The corresponding real-life filming location

These do not always agree, and there are significant gaps in the reference for the first two, so finding the right compromises can be tricky. For instance, this shot in Sorcerer’s Stone shows Neville’s POV as he nearly impales himself on a statue:

I’m not sure about the background, but the foreground architecture is all CG, and it matches neither the real-life location nor the miniature…although the corresponding spots at the location and on the miniature are never shown onscreen. To make matters worse, in the live-action location shots that follow, the statue (which I believe was installed just for the film) has moved to a different corner of the structure. So there is no single coherent reality for me to replicate.

In this particular case, my approach will be to ignore this quick shot altogether and aim instead for the real location with the added statues and other set dressings. But I’ll save that for the next post.

What Was There Before the Hogwarts Greenhouses?

It’s not a question that you could answer just by watching the films. Here we have to rely on behind-the-scenes shots and technical drawings from Sorcerer’s/Philosopher’s Stone to reconstruct this area in its original state.

But first, I knew I needed to finish up this area as seen from Chamber of Secrets through Half-Blood Prince! I finished the curtain walls and added lawns:

Here’s a cool POV shot coming down the back steps of the Durham building:

That’s a wrap for this area in the Prisoner of Azkaban 3D model! But what did it look like at the time of the first film? Well, you still had curtain walls surrounding a large, L-shaped lawn, but the walls weren’t quite as far from the castle, and instead of the domed conservatory acting as the entryway, you had this relatively simple, squarish, Alnwick Castle-inspired building:

This side of the building is actually seen in a couple of shots in the film, but I haven’t been able to find as much detailed information about the other sides – in particular, the opposite side that faces the castle proper. For that facade, I’ve just used the same details as what you see here, but I can’t deny the possibility that some of the details were a little different. (I wonder in particular if they really would have put the Hogwarts crest on the other side.) Unless I find elevations or images of that part of the miniature, I may never know…when the greenhouses and conservatory were added in COS, this small gatehouse disappeared forever.

Anyway, here are a couple of before-and-after sliders to play with! On the left is the Sorcerer’s Stone castle; the right is Prisoner of Azkaban. (The changes we’re currently focused on occurred in Chamber of Secrets, but you’ll of course see some Azkaban changes too.)

I’ll wrap up this post with a view of some additional work I did next on the west side of the Alnwick Castle warder’s tower. Here there are again some details that differ a bit between the VFX miniature and the real-world filming location; I’m primarily going off of the miniature, though Alnwick does provide invaluable reference as well. I guess you could say my goal is to capture the shared imagined reality that the model and the location both help bring to life.

The two contenders for my next area of focus are the transfiguration/middle/Durham courtyard and the training grounds tower. I’m much more excited at the prospect of doing the latter, but I think I may tackle the courtyard first. Be sure to subscribe to be notified with future updates!

Finishing the Bell Towers – “Azkaban” AND Original Versions!

Here we go – those bell towers need to be completed. I finished the intricate openings and decorative motifs in the middle parts of the towers. Fortunately, these never changed in any of the films, even when the tops of the towers changed, so I only had to create them this once!

Then, to complete the bell towers, I added the tops of the towers, which are very similar to the top of the central tower – just shrunk by about 23%, and with a few minor design differences. I was grateful for this not only because it allowed me to reuse elements from the central tower, but also because I discovered a mistake in the central tower in the process. All fixed now!

Of course, there are two versions of the bell towers: the original design, and this Prisoner of Azkaban redesign. With the latter complete, I decided to switch over and do the former as well!

Sadly, photogrammetry is no help when it comes to the original tops of the bell towers, but their simple design is pretty easy to eyeball. A few of the smallest details were educated guesses – for instance, I’ve added windowpanes in a few areas that could just be openings.

Anyway, enough talk – let’s compare the two designs! Drag the slider below to compare the original Sorcerer’s Stone design (left) to the Prisoner of Azkaban redesign (right). (The smaller tower above the Long Gallery will also come and go, since that was added in Chamber of Secrets.)

Here’s a reverse angle:

Surprise – there’s the original design of the central tower, too! I snuck that in there as well.

Viewing the whole castle from lake level, you can really see what a difference this simple redesign of these three towers made in the castle’s overall silhouette and character. My model is also looking a lot more complete overall!

Adding the wall between the bell towers was easy, since all of its elements are similar to stuff I’ve already created. I briefly considered tackling the greenhouses next, but then I got distracted by the adjacent walls that bring us to the training grounds tower and the middle courtyard, which will probably be where I go in our next blog post.

In the meantime, Ms. Rowling continues to tweet disappointingly misguided things about transgender people. For what it’s worth – if you, dear reader, happen to be trans, non-binary, or a member of any other oft-marginalized community, know that this Hogwarts (incomplete though it may be) will always be there to welcome your awesome self, and so will I.
