heyas; you can get a decent deer body out of the horse if you mess with it. i'm working on a horsealope, but that uses horse head morphs rather than a new head. the technique, though, isn't really that different from other types of cr2 geometry substitution. you don't need step 3 (i think you meant make the number of vertices the same...?) if you weld the new head on, then cut it back off, like i stated above. :)
