The cheetah texture is missing in the download, but you can get the original model here: https://www.blendswap.com/blends/view/57756 (both links in the description go to the velociraptor model). Also, if anyone is seeing the texture showing up weird and stretched, note that you MUST have BOTH models (the original and the voxelized one) occupying the same location. If one is off to the side, you will get weird projection errors).
Additionally, it is possible to snap during scale: just select the snapping icon beside the "magnet" and choose"affect" > "scale".
