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.

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.
