I made my first "tuned" model for Sketchup (some 3D modeling program) and my brother (
suprapuffy) taught me the essentials for using it. :3 I like it, but some things are too frustrating like modifying the parts to fit "perfectly". :\ Unfortunately, it has a nasty habit of having some "magnetic" effects when I try to move the parts around or resize it. Nevertheless, I'm content with the final product (not as good as what the game people do, but close enough.) Obviously though, I did say "Modify", so the original model is not mine to begin with.
