Ok so I was trying to vertex hack Yoshi's hands so that they would be more like claws. I followed the steps of this video tutorial perfectly:
But in Brawlbox, instead of showing the hands being extruded out, it just shows a load of random polygons on the body flying out in random directions. I think it has something to do with Anim8tor since when I did a vertex hacking process in 3Ds Max without Anim8tor the vertex hack worked fine (reason I don't just use 3Ds Max though is 1) I have the trial version which doesn't last much longer and 2) I am more familiar with Blender.
So basically question is: Is there any way to vertex hack in Blender WITHOUT using Anim8tor?
