Open Game Art has just released some specially-commissioned free Creative Commons figures, intended for Blender games. The first is the Lizard Man by thecubber. I’ve converted it for iClone, and it can be animated using Motion Edit. At less than 9,000 faces, you could easily put a half-dozen of them into a swamp scene. Included in the pack is the working .fbx file, the original textures, the iClone iAvatar and its .ini, and a ready-lit iClone project file.
