Marmoset - Weird Lines appear on imported psed character

greenkangaroo

New to marmoset and I am trying to render this character. She's rigged in maya and after posing her, the imported fbx (right) appears with all these weird lines! Compared to the unposed model on the left, which looks fine. They have the same UVs. I tried copy pasting UVs from the t-pose onto the new one, tried posing the t-pose model from scratch, and it still happens when I import it to marmoset. Any help would be appreciated I've been trying to solve this for hours

Add colors or the uv tiling map, it looks like stretching to me if the posed is in fact u.v.'d.  i do not know maya stuff I've reviewed some things but not really fluent enough to help on the maya side only in what might be happening on the uv side.

map to use to view stretching click me, wiki uv map jpg if you do not click search uv tile mapping for 3d in images look for colorful squares with letters and numbers
