OF course.

I know it's because  . . Well, it's like this. The original obj file would stretch and show gaps in the seams when I put mesh smoothing on it, and I had already modified it slightly to remove some areas  - but if you just load it without using the original CR2 it won't move with the character, so I  merged the edges so they would not split and just use it that way and it works. It probably does not load beacuse it's "disobeying the rules" in 4.5.
