My current project:
I've seen some photos of a steampunked R2D2 on 9gag and later on devianart, so I've decided to do that as a CG model in case that the refs are realistic models.
This is what happens so far, some little details are missing, some parts need to be rebaked. Something around 10000 Tris (damn cylindrical shapes) and a 2k texture.
Prsented with 3dsMax using Xoliulshader 1.6
