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!

Finishing the Training Grounds Tower (COS-OOTP)

Still not sure how I want to handle the statues on top of the Alnwick Castle structures, so I’m hopping back over to the training grounds tower.

Part of this little corner still needed to be filled in. It’s hard to find good reference for that spot on the miniature, and it does seem to be somewhat different from the real thing at Alnwick. I decided to just do my best (and add the footpath where Hagrid drags the Christmas tree through the snow):

There are a few torches that show up over here in some shots in Chamber of Secrets, but I’ve elected not to include those – their positions aren’t always clear or even consistent from shot to shot, and I’m not sure whether they were ever in the main miniature.

Around the other side of the structure, I’ve accepted the difficult truth that I may never find adequate reference for certain details. I’m using the real structures at Alnwick to fill in the gaps as best I can. Fortunately, some of those real-world details are visible in the background in Sorcerer’s Stone, so I feel justified in including them.

This shorter structure on the right corresponds to Alnwick Castle’s 19th-century chapel, and from what I can see, it seems to have been a pretty exact recreation in the miniature:

Incidentally, see that rectangular depression a ways to the left of the chapel, above the arched recessed windows? In real life, the heraldic symbols of the Percy family are there. In the Hogwarts miniature…I can’t tell. It’s too tall to just be a Hogwarts crest. So I’m just leaving that blank for now. If you’ve got closer images of the miniature here…please send them! I’m always on the hunt for new rare photos or blueprints of the miniature.

In the meantime…here’s the complete training grounds tower, as it existed from Chamber of Secrets through Order of the Phoenix!

Fun fact: In the last render above, we’re sitting on the clock tower courtyard roof. The foreground cylindrical tower on the far right is of course Gryffindor Tower.

You might notice that I’ve removed the Alnwick Castle barbican/gatehouse and adjacent walls. Or rather, I’ve moved them so they don’t exist in my Prisoner of Azkaban model anymore, since that area will be covered up by hills. Don’t worry – those structures still exist in my nascent Sorcerer’s Stone model, and they’ll become part of my Chamber of Secrets model too.

More Training Grounds Tower

Wow, I did not mean for the last couple months to slow down so much! I’ve been busy with some unrelated projects. My apologies for the radio silence! But I thought I’d at least share a brief update.

As you can see in the new render above, I’ve been continuing to work on the training grounds tower – the version that existed from Chamber of Secrets through Order of the Phoenix. I can see why Stuart Craig took the opportunity to replace it with a much simpler tower in Half-Blood Prince, but I do have a soft spot for this rather charmingly awkward design.

One thing I’d never really thought about was the huge number of very diverse and irregularly spaced windows on this structure. I decided to start carving out the holes before worrying about the frames and panes; that way I could easily make adjustments. My reference images are limited for some of these areas…I’ve had to accept that some of my window holes may be off by a few feet or have a slightly different design:

It ain’t perfect, but it’s a start. The bottom parts of these walls are the hardest, at least if the goal is to be accurate to the miniature. You would think they’d be identical to the corresponding spots at Alnwick Castle – spots that are even seen in the backgrounds of the location shoots in the first film – but you’d be wrong. I’ve seen enough to know that there are differences…just not enough to know exactly what every window looks like. Looked, I suppose I should say…it’s certainly not part of the model anymore, and who knows what happened to it.

Anyway, as I said, I’m pretty focused on some other projects at the moment, so I apologize if there’s another long gap before my next post!

COS-OOTP Training Grounds Tower, Cont’d

Whew, sorry for the long delay…the months of sitting at my home desk have taken their toll on my arms, and I’ve had to significantly limit my computer use. This will be a shorter post as a result. I’m starting physical therapy soon…if you’re feeling particularly generous and you want to help support my recovery, my Venmo handle is @Joe-Cardello, for what it’s worth. 🙂

Anyway, let’s continue with the version of the training grounds tower that was seen throughout the middle of the Potter series, including Prisoner of Azkaban. As we work our way around to the west facade, my reference material becomes even scarcer, but I’ve got just enough to piece it together in a reasonably accurate way. I started with plain walls, deciding to add the windows and so forth later:

Here’s a view from overhead once I’d roughed in the main shape of the building. At this point, I wasn’t worried too much about cleaning up the intersections between walls and objects…I just wanted to make sure the layout made sense three-dimensionally:

You can see just a bit of the tiny courtyard in the middle. That’s one area for which I truly have zero reference (other than the basic floor plan). It roughly corresponds to the cobbled inner courtyard at Alnwick Castle, which was actually used in the location shoots for the first film, but the version in the miniature is much smaller and it has a different shape because of the way the Alnwick floor plan was reconfigured around it. So the layout of any doors, windows, or other decorative elements on that part of the miniature sadly remains a mystery.

As I said, I have less progress to share because of my ergonomic issues, not to mention the simple fact that this is a tricky structure to figure out. But I’ll at least fill out the rest of this post with an aerial overview of my POA castle so far:

Take care of your body, take care of your mind, and don’t be an ass to people who identify as transgender. See you soon!

Starting the Training Grounds Tower

Holy crap! I can’t believe we’ve arrived at the final major tower of Hogwarts! I’ve been eager and afraid to tackle it because of its complex geometry and the limited reference available. Let’s jump in!

The training grounds tower was added to the original castle out of sheer necessity. Alnwick Castle was used as a major filming location so they needed it to be present in the miniature. Stuart Craig’s team tweaked its footprint a bit and built it up into a much taller complex of towers; the bottom floors just looked like Alnwick while the upper floors took their stylistic cues from the original castle’s other conical turrets. Evidently Mr. Craig didn’t like the vertical extensions, because they were totally redone for the second film in a style that slightly foreshadowed the more Gothic look that would take over in the third film. (Interestingly, some COS shots still feature the SS version.) That revision stuck around till Half-Blood Prince, when it was replaced with a single tower echoing the bell towers’ design.

Since I’m working on the Azkaban castle right now, it’s that second iteration of the tower that I’m focusing on. And “focus” is indeed the right word, because I’ve spent a lot of time just staring at reference images and…thinking. Trying to piece it all together. Eventually, I started working on the facade toward the right:

This is the project’s first render with the OptiX denoiser, which wasn’t compatible with my GPU till Blender 2.90. Denoising is critical with path tracers like the Cycles render engine, where speeding up the render introduces more noise. I was using Open Image Denoise before, but OptiX is faster and it’s retaining more detail, so I’m pretty stoked!

Anyway, training grounds tower. It’s proving as challenging as I feared/hoped it would be. The modeling itself is not particularly difficult, but the paucity of high-quality reference images makes it difficult to piece together all the details, especially since I want to get the scale right.

I’m keeping an eye on the original version too, since the lower section is identical and I want to make sure I can reuse it without any issues.

In a twist that will shock precisely zero longtime readers, I’m finding lots of small discrepancies between shots of miniatures, location shoots at Alnwick Castle, CG long shots, etc. As usual, I’m striving for something of a happy medium, but weighted toward the main 1/24th-scale miniature.

There’s still a lot more to do on this structure, but it’s been 10 days since I last shared my progress and I think I’ll save further progress for my next post.
