South Wing Odds ‘n’ Ends

As we’ve seen, POA featured some significant additions to the castle’s architecture, many of which were anchored by the new clock tower in the southwest corner. The last remaining piece of this section was the small gatehouse at the end of the wooden bridge. This came together easily; the only real question was how big to make the torch, since its size (relative to the building) differs significantly between the miniature and the full-sized set built at Glencoe. I ended up using the same scale as some of the castle’s other torches, which resulted in me kinda splitting the difference between the two sizes.

Believe it or not, that brings the POA additions to something of a complete state!

The south wing as a whole is still not complete, since I haven’t touched the quad interior due to scarcity of reference material. I also still need to add the walkway that connects the Chamber of Reception to the quad, but I’m holding off for the same reason.

Knowing this, I decided it was just about time to turn my attention to the castle’s north wing, much of which is derived from Durham Cathedral and Alnwick Castle. There were just a few odds ‘n’ ends to finish up first, like the fleur-de-lis pattern at the back of the Great Hall (bottom right):

Another miscellaneous item was the tree in the clock tower courtyard where Buckbeak’s executioner sits to sharpen his blade. It was fun creating its forking, branching paths by hand, following what we see in the film for the trunk and larger branches, then just going crazy with the smaller branches. I allowed Blender’s Skin modifier to bulk it all out into a basic three-dimensional form:

Whoops…I realized I’d forgotten to add the steps leading up from the courtyard to the wooden bridge. I added those, sculpted a bit more detail into the tree trunk, and used a particle system to add some leaves.

Next came ivy to help the courtyard feel a little more overgrown and wild:

I also spent some time grappling with Blender’s Mantaflow fluid simulation engine, trying to get convincing smoke to furl from the castle’s chimneys. It took the better part of a day for me to figure out that my baking errors stemmed from an apostrophe in the cache folder path (a folder descriptively named “Joe’s Stuff”). With that finally resolved, I was able to get some smoke in there:

After all the frustration, I really like how it turned out! I think that’s a nice note upon which to end the work on the south wing, at least till I can find more reference for the POA-era quad. Next we turn to the north wing, starting with the Durham section!


Completing the Wooden Bridge (POA Edition)

With the basic structure of the wooden bridge in place, I next set out to adjust the support beams below. The bridge spans a ravine and its cross beam patterns do vary. Paying close attention to their arrangement in the original miniature, I first modified the half closest to the castle:

Then it was just a matter of duplicating the structure to the far side and tweaking a spot where it’s not quite symmetrical:

This brings the bridge to a complete state…at least, without all the shaky imperfections that give the original its charm. Time to get those in there.

My weapon of choice was Blender’s Mesh Deform modifier, a nondestructive tool that allows you to manipulate one object’s shape and have it affect the shape of another. I created a much, much simpler version of the bridge – really just a 3D envelope to roughly surround it – and manually pushed different sections around to approximate the swaying structure seen in the films. Blender obligingly shifted the detailed model of the bridge to match.

Just for fun, here’s the simplified envelope visualized with a translucent material around the actual bridge model, prior to any distortion:

And when I warped that envelope (twice due to some annoying lost work), it made the detailed bridge underneath look this!

(This is after breaking apart the roof into some separate chunks with their own local coordinates so that the shingle texture would map correctly onto them.)

I’m feeling quite happy with this! It’ll look a lot better once I’ve added terrain, of course. And even just adding the gatehouse at the other end will help. I think that’ll be my next task.
