Thanks for the heads up. I'll just go with plan b, which is make the mesh in SU (easier that way) and import into Milkshape for animating.

Hello fellow Sketchup users,
I'm a game developer using Sketchup as a level editor for my own independent games. So far, I'm really impressed with the results. I haven't been using it for that long, so I don't know most of the ins and outs of the program, but I like what I see. My question is if through Plugins, could SU be used to create animated models for games? For example, could I create and animate a character in SU and use them in my game?
