GOF Quad & Viaduct Areas

The next additions to the Goblet of Fire castle were the “pepperpot” and the foundations of the viaduct courtyard:

I like that angle!

Next, I moved back around the backside of the Great Hall to begin adding the quad building. The south wall was changed in GOF – a new archway acts as another entry into the quad itself.

Speaking of the quad interior, check out this POA/GOF before-and-after:

I should reiterate that some parts of this are a little speculative…I don’t know for sure that the lower floor, the cloisters, and the fountain were still there in POA. But the best evidence seems to point toward that being the case. And as a reminder, the balustrade toward the bottom left in the POA version is pretty speculative too. And of course, if you’ve played the video games a lot, the lack of cloisters on the right might look pretty weird, but as far as I can tell they never came back after POA.

I’m starting to notice an interesting shift in myself. I’ve tended to think of myself as having an especially big soft spot for the first few castle designs. But as I move the virtual camera around my growing model of the GOF castle, I’m appreciating its aesthetic more and more. It holds up really well from a lot of angles. They did a really good job of choosing camera angles that flatter the earlier castle designs, obscuring some of the clunkier elements. But the GOF castle doesn’t really have many bad angles to begin with.

Anyway, here you can see me preparing to add the viaduct:

And now with the viaduct in place:

It may seem like that would be a simple matter of dropping in the existing viaduct, but it actually took some effort. The switch from the Chamber of Reception to the courtyard causes the whole viaduct to swivel a little, and I had to compress it a bit to fit the new angle. I wonder if the original modelmakers had to rebuild the whole viaduct from scratch or if they were able to squeeze the original viaduct into that space somehow?

Anyway, my next move was to drop in a whole bunch of stuff from the POA model that didn’t change for GOF, creating a much more complete castle:

As part of those efforts, I also finally added a missing detail at the base of the Dark Tower – a little entry stairwell that’s hard to find shots of. Here’s my best attempt at bringing it to life, based on the available information:

The main elements the GOF castle still needs are the owlery, the boathouse steps, and the terrain. Saving those for a future post!

The Transfiguration Courtyard

Time for a Hogwarts feature that’s right out of Durham Cathedral, at least in its original form. The cloisters were used as the filming location for the “middle courtyard” or “Transfiguration courtyard” in the early films, though it was later represented by a similar courtyard at Oxford and then by a set at Leavesden.

I first spent a morning working on under-the-hood tweaks to hopefully improve the file’s performance – downrezzing overlarge normal maps, replacing duplicated objects with linked proxies, decimating some meshes that had gotten too dense, etc. The hope is that my computer will be able to handle the file a little more easily moving forward. No sexy renders to share for that, though, so here’s a cute puppy photo instead.

Anyway, back to Hogwarts! A big question cropped up as I was compiling my references: How much detail do I put into the cloisters – specifically, the doorways that lead to other parts of the castle? These are seen in the location shoots in the first two films, but at least some of these were evidently left out the miniature. (They never would have been visible in the film, so I can appreciate the decision to focus elsewhere.) Furthermore, the south walk (which corresponds to the east walk at Durham) changed repeatedly over the course of the films, and I have no idea what the cloister interior looked like at that point.

I figured the most reasonable approach would be to create the complete courtyard without those doorways and then see if I could get away with it in my renders. I started with the tracery of the cloisters and a basic ground plane:

This part was easy because I’d already built the clock tower courtyard – its cloisters contain a lot of design elements adapted from Durham Cathedral.

The fountain in the center of the courtyard was next, and this one’s going to give me some trouble later on…not because it’s hard to create, but because it’s unclear exactly when it vanished. Let’s break it down:

  • It was created for the first film, apparently as a set dressing that sat on top of the lavatorium (monks’ handwashing station) that sits in the middle of the courtyard at Durham.
  • It’s still there in the second film, both on location and in a bespoke 1/8th-scale model of the courtyard used in an overhead establishing shot.
  • The center of the courtyard is never visible in the third film, so that one’s a question mark.
  • As I mentioned, goings-on in the courtyard were shot at Oxford instead of Durham Cathedral for the fourth film, so the location looks totally different and won’t be reflected in my model. There is an aerial shot during the First Task when we briefly see the Durham courtyard, but if the fountain is there, only the very top of it is peeking over the roofline.
  • No idea in the fifth film…
  • In the sixth film, the courtyard was realized as a set that included the base of the Astronomy Tower. (I suspect this was a revamp of the viaduct courtyard set, which I suspect was a revamp of the clock tower courtyard set.) There’s no fountain in that set, but that set is far from a perfect match to the miniature. I can’t find any shots of the center of the courtyard in the miniature, but the fountain is gone from the technical drawings and I’d imagine the same is true of the miniature.
  • In the final film, the fountain is again missing from the technical drawings, and this is confirmed with a CG overhead shot of the area.

With all that in mind…until I can find more reference that confirms which changes were made when, I’m just going to assume the fountain lasted till the sixth film, at which point it was removed and never came back.

Anyway, I added the fountain and started the sewer grate. I also added the benches, which seem to have been more set dressings. You can see in this render that I’ve finally mirrored the east walls of the Long Gallery onto the west side, too:

That’s the first render I did with the new Blender 2.90. It’s got some great new features, but it kept crashing when I attempted to render. After some troubleshooting, I figured it out: this version of the software doesn’t like my old smoke simulations. That’ll need to be addressed, but for now, I’m afraid the hearths of Hogwarts have gone cold.

That structure in the top left corner of that render is a newly-added Durham Cathedral transept, the last missing piece of the Long Gallery. In the first film, this one was a simple mirror image of the one on the other side, but when the Dark Tower (center) was added in Prisoner of Azkaban, this transept had to be shortened a bit, resulting in a slightly asymmetrical footprint that lasted right through the end of the series. Easier to see from the air:

As you can see, the one to the left of the central tower isn’t as long as its counterpart on the right.

One interesting thing about this courtyard is that each of its four sides has a different look. I next took care of the north wall, which corresponds to the west wall at Durham:

You’ve no doubt noticed that the cloister is still roofless – I decided to save that for after the surrounding walls were built. Speaking of which, here are the last of them:

It’s hard to find detailed reference for the wall on the right (above the two benches) in the miniature. Its design is similar to that of the corresponding wall at Durham Cathedral, but there are some differences. To make matters worse, there are some apparent discrepancies in the number of windows in the various Hogwarts images available, but there’s a good chance that what I’ve done is accurate to the state of the main miniature at the time of POA. And if not, it’s at least quite close – it could be that there are supposed to be six windows on the shorter part of the wall instead of five.

Anyway, the only remaining step was to add the cloister roofs! With these in place, the answer to my “big question” became clear: No, I didn’t need to add doors and other details inside the cloisters. They simply aren’t visible unless you’re actually inside the cloisters, and I’m okay with not having detailed views inside there. So with that in mind…voilà, the complete transfiguration courtyard!

Incidentally, I love that structure just above the center of that render, below the DADA tower. It was added in the third film when the DADA tower got shifted over a bit, and it’s basically just a Durham Cathedral transept, except, like…a standalone version. Something about it tickles me. Naturally, everything will look better once that wall next to it has an actual building behind it, but that’ll come with adding the final major piece of the main castle: the training grounds tower!

The Long Gallery & Starting the Bell Towers

Work on my 3D model of the Prisoner of Azkaban castle continues! The area that corresponds to Durham Cathedral’s north transept is now complete:

I shifted my way attention to the adjacent walls that correspond to the cathedral’s nave and north aisle, otherwise known at Hogwarts as the Long Gallery. I was surprised to notice that the windows and buttresses are not evenly spaced. In fact, the upper windows don’t even align with the lower windows. I fought this briefly, thinking I must be mistaken, but nope, I’m pretty positive none of this stuff lines up in the miniature – and not in ways that match the imperfections of Durham!

I wanted to match the miniature as closely as I could, so I started by adding placeholders for the bell towers at the other end of the Long Gallery to help me lock in my spacing:

The stand-ins are shorter than the talent, and their faces are kinda blank, but hey, what are you gonna do.

At this point I discovered that my entire Long Gallery area was about a foot too far east, so I took a few minutes to shift it over and swivel the viaduct accordingly (a whopping 0.25°). A foot’s not a lot – at 1:24 scale, that comes out to half an inch in the miniature – but it helps to line things up as closely as I can.

With that done, I blocked in the walls and roofs of the long gallery:

Then came the details, with all their subtly variable spacing. Here’s an orthographic view from the side – a perspective-less elevation view, in other words. All the misalignment is totally intentional, and it should be pretty accurate (although I made further tweaks after this render).

Of course, it’ll look better once the far side is enclosed as well; I’m not working on that courtyard side yet.

In the meantime, my next task was to create the 15-foot-wide octagonal tower on the roof of the Long Gallery. This was added in Chamber of Secrets; my guess is that it was a purely aesthetic decision, perhaps motivated by the fact that the establishing shot of the greenhouses shows that area more clearly than we had seen in the first film.

Pretty quick add, and it never changed in any of the later films. Just gotta make sure I exclude it from the eventual Sorcerer’s Stone version of the model!

Next up? The bell towers! While the central tower isn’t very similar to the one at Durham Cathedral, the bell towers have a lot more in common with their Durham counterparts, the North and South Galilee Towers. In fact, the basic impression of the original design in the first two films is that they’ve simply knocked a few of the pinnacles off and added a conical roof to each tower. (Closer inspection does reveal some subtle differences in the details, as with all the Durham areas.) In Prisoner of Azkaban, the conical roofs were replaced with taller belfries and octagonal spires that echo the redesigned central tower, but the lower sections still bear a striking resemblance to Durham Cathedral. They also get a lot more intricate than the central tower, which makes them a little intimidating. I decided to start with the bottom portion, which is all based off stuff I’ve already made:

Now for the hard stuff! Okay, it’s not exactly hard…it’s just…a lot.

Halfway there:

The openings are tricky. In some shots in the early films, you can very unambiguously see straight through from one side to another, but in some photos of the miniature from the Warner Bros. Studio Tour, it looks like there are interior walls. After finding other photos that seem to show straight through in the Studio Tour as well, I decided to keep mine hollow, as you see above. Hopefully that’s still accurate to the later films.

Next time we’ll finish the bell towers, add the wall between them, and continue around this northern part of the castle!

Complete in 3D: Gryffindor Tower (POA Version) and the Dark Tower!

The rest of the work on the Prisoner of Azkaban version of Gryffindor Tower proved pretty easy. The remaining windows came together quickly.

I even added this mysterious pipe-like thing that juts out directly over Harry’s window (near the top middle of this render). No idea what it is…it’s been there at least since Goblet of Fire, probably since Azkaban or earlier, and it’s still visible to this day in the main VFX miniature at the Warner Bros. Studio Tour in London. If you happen to have any idea what it is, be sure to leave a comment!

You also can see I removed the suspension bridge at the lower left. It’s not completely deleted, just moved to a hidden layer; it needed some reworking that I just don’t want to deal with at the moment. It’ll come back eventually.

Work then moved on to the Dark Tower. Whereas Gryffindor Tower was just revised a bit for the third film (mainly making it taller), the Dark Tower was an entirely new addition. Its purpose was to provide a visually dramatic location for Sirius Black’s cell at the end of the film. It sits roughly where the real-world Durham Cathedral chapter house structure sat in the first two films.

The basic structure of the tower is super simple – just a slightly tapered cylinder with an off-center pyramidal base. Sirius’s cell is perched right on top; the render above shows the front wall of the cell beginning to take shape. I kept going and eventually finished all the detail on the top of the tower.

The most interesting challenge ended up being those four stone gargoyles near the top of the tower. These are never seen up close in the films…they pretty much just look like vague oblong shapes with a skinnier protrusion at the end. But I started doing some digging in the various video games released around this time, and I found some much closer shots. To my surprise, the games reveal a design that looks more like a vulture than anything. Now, the games obviously use 3D assets built specifically for the games, and the design can totally change in the process of translation from film to game. But these closer shots seemed consistent with the blurry shapes visible in the films, so I decided to just go for it. They gave me some fun practice with sculpting and retopologizing.

The rest of the tower really doesn’t have much more detail on it, so I’m calling it finished! Here’s a render showing the completed tower with the rest of the model so far. Fun fact – Harry’s window actually looks pretty much straight at the tower where his godfather ends up being briefly held. That’s kinda sweet. Whoops, this isn’t true – the Defense Against the Dark Arts tower totally blocks the view of the Dark Tower from his window. Never mind!

I’m planning on starting what fans have been calling the Defense Against the Dark Arts tower next. See you soon!
