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!
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.
