You are welcome. I'm glad to help! By optimizing I mean "repairing" The topology, adding loops where there are joints for the characters, and make a UV channel for lightmaps for environment stuff. Mixamo exports FBX format.
Gotcha, some of that sounds like a foreign language to me but for now I'm just going to concentrate on making some voxel art and getting it animated to the best of my beginner ability. :) Thank you again for taking the time to respond.
