This will be the first miniature set I've built on my own (especially this large). It's a rather complex design, so I actually did a lot of planning in 3D before I even bought any materials to build with.
The idea is: because I have such a limited amount of space, and because the character needs to travel through a large forest while mostly running, the best solution I could come up with was to green screen the character and do the whole set in 3D....
I kinda threw up in my mouth at that idea though, so I decided... What the heck... I want this to be as true to stop-motion as possible, so I'll build an animated set. And that's what I've been doing the last few months. :)
