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!

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!

You Can Never Have Too Many Greenhouses

The 3D model of the Prisoner of Azkaban castle keeps chugging along! After completing that first greenhouse, I duplicated it three more times:

These four all share the exact same design, but then there are four more along the east side of the Durham area, and their dimensions are a little different, so I had to create (and thrice duplicate) a new variation over there:

And then at last there is Greenhouse Three, which is a smaller lean-to on the castle’s outer wall. (You can catch a glimpse of it in the above render.) This is the greenhouse where the Herbology lesson with the mandrakes takes place. It’s got its own unique design, so I took care of that next. Some of the dimensions here don’t line up quite as precisely as I’d like, but I’ve tried to minimize the number (and visibility) of compromises as much as I can:

You can also see that I’ve also added rust, adjusted the weathering of the wood, and started with the footpaths between the greenhouses. I even threw in one of the largest vines that snakes its way out of the greenhouses, visible toward the bottom right:

In the background, you’ll see that I’ve begun the curtain walls around the greenhouse area. These were actually there in the original design of the castle, even before the greenhouses were added in Chamber of Secrets; they just had to be pushed outward a bit to accommodate that addition. Here’s a better view of their progress:

See where the wall stops on the right? That’s going to be the site of the final greenhouse structure, the domed conservatory that also acts as the only way out of the greenhouse courtyard and into the grounds. But I’m going to save that for the next post. I’m hoping to even share something I’ve never seen before: an interior view of that conservatory*!

In the meantime, I’ll leave you with a slightly different aerial view of the POA model so far. Still plenty more to be done, but we’re getting closer!

* If they happened to include the conservatory interior in any of the video games, let me know! I haven’t played them but I’ve looked through longplays on YouTube and never spotted it.

Starting the Greenhouses

Hogwarts got its greenhouses added in Chamber of Secrets. They sat undisturbed in what was formerly an open courtyard until Deathly Hallows Part 2, at which point some adjacent architecture was removed and the greenhouses expanded a bit to fill the empty space.

My own 3D recreations of these greenhouses provided some fun challenges right off the bat. As I alluded to in the previous post, I was surprised to realize that they are not all identical. I mean, I knew that there was a lean-to attached to the wall of the castle as well as a domed conservatory out front, but I’d assumed the other greenhouses were octuplets. No such luck. The ones that run parallel to the Long Gallery aren’t quite as long as the ones that run east-west along the north facade, though they’re made of the same basic building blocks.

As always, I wanted to get the details and dimensions right. Without much in the way of detailed technical drawings, I resorted to making some quick-‘n’-messy diagrams to organize my thoughts and measurements.

Quick and messy, like I said, but it really helped me figure out how to proceed with the modeling. I started framing just one wall of just one greenhouse, laying out the largest support posts every 10 feet. Some of these will eventually have sculpted dragons on top, but those’ll come in a future blog post:

Blender’s Array modifier makes it easy to just work on one segment and have all the others update accordingly. No textures at this point either – I knew the white paint would later need to be scuffed up a bit.

Adding more details, temporarily pretending that the greenhouses don’t have any doors:

The familiar question of whether to follow the miniature or the set cropped up yet again. Actually, it’s more complicated. The greenhouses didn’t show up often in the films, but they got a glorious establishing shot in Chamber of Secrets. The VFX team put together a very impressive shot that moves across the lake, over the grounds, and right through an open window into the lean-to, AKA Greenhouse Three. The shot combines the 1/24th-scale Hogwarts miniature (and CG background) with a live-action plate shot on the greenhouse set, and it’s pretty seamless, especially for the early 2000s. But the camera has to go right up to the greenhouses, exposing a lot of detail…and at 1/24th scale, some of that detail wasn’t going to hold up. So they built separate 1/8th-scale miniatures of the three greenhouses the camera would get closest to. For whatever reason, while those larger bespoke miniatures match the design of the set, the main castle miniature is slightly different. I’m mainly talking about the windowpanes – they’re narrower and more numerous in the main castle miniature.

Sooooo…what to do? Follow the set and 1/8th-scale miniature, or follow the 1/24th-scale miniature? I take these decisions on a case-by-case basis, and for the greenhouses, I ultimately went with the wider windowpanes from the set and 1/8th-scale miniature (for a variety of reasons).

Here we go – doors and details and preliminary materials.

Starting to add the beams for the roof:

Hey, it looks kinda like a greenhouse!

By this point, I had been really debating exactly how much interior detail to do. This project file just keeps getting bigger and bigger, which means my computer has an increasingly hard time keeping up. It’s thus in my best interest to only include the details I need – but of course, the greenhouses are rather transparent, and I still wanted to them to “read” correctly from the outside. Once I had them fully enclosed, I was able to see how the materials interacted with the light and decide how much interior detail I needed to include. Not much, it turns out, as long as I don’t let the glass get too crystal-clear:

Some of the geometry got slightly messy as I went around the corners of the greenhouse, trying to respect all the various reference images as much as possible, but I’m pretty happy with the result:

For a moment, I thought all I had left to do was sculpt the decorative dragons on top, but then I remembered that I needed to pop the roof hatches too – otherwise, how would the camera float in for that great shot in COS?

(These are all open at random angles, BTW…I’m anal, but not anal enough to match them exactly.)

Anyway, I’ll be sculpting the dragons next, but we’ll save that for a future post, hopefully in video form. I’ll also need to create all the other greenhouses using the same components. See you next time!
