This model of a Western Diamondback Rattlesnake (Crotalus atrox) is fully rigged with a dual FK/IK system so you can choose which way you prefer to animate. The rig is cleaned and I locked everything that down that shouldn't be moved, so the animator won't accidentally break anything.
There are polySmooths in the history, and they can be turned off and/or deleted. I rendered with 2 divisions, the count was 21288 polys and 21322 verts.
Materials are Maya (blinn).
Textures are included and the body map is 2048x2048. It comes with a normal map and a specular map.
FBX is skin with base joints only, no controllers or constraints.
