are you talking about Desktop Mate or Mate Engine? it works in the former, but in the latter he does not load. i assume maybe it's an issue with scale?
they are two separate programs, sorry if my comment was confusing at all.
@onlyheresearch , that's strange. I had tested it on desktop and it worked perfectly fine. It also seems to have worked fine for others. Are you sure it is a problem with the model?
