The standard Mincraft character (cycles and internal) that can be re-skinned to your liking. I have rigged this as conservatively with no elbow or knee joints to get the authentic Minecraft movement. I have included the standard Steve skin and the zombie skin which I have scaled up in photoshop to preserve the hard lines because blender does not do vary well sampling 64 pixel wide images. If you want to put a custom skin in I suggest that you do the same.
Instructions for scaling skins-
Photoshop: go to image/image size/ then select nearest neighbor and enter 4096?×?2048
Gimp: go to image/scale image/ then set interpolation to none and enter 4096?×?2048
