As Forceboat said, I'm creating the mesh for IG-88 for the Shadows of the Empire Mod. You can check out the current status of the mesh here:
The mesh is almost complete and then it would be time to UVW map him, build his skeleton, weight, animate, etc. etc. In short it's going to be awhile before IG-88 is done-- and even then he will only be released in Volume II (second demo).
We are currently focusing all our efforts on the resources needed for Volume I and I am currently modeling Dash Rendar (screenshots should be posted on our public forums soon).
If you know of any modding talent, send them our way.
