XSI freezes when I try to export this particular obj to msh. I've never gotten this problem before and I don't know what's causing it. When I root select "dummyroot" and click export msh, XSI begins exporting but freezes at "Processing Model (name)...2/5".
The bottom box reads "CGA_GetMaterialNames "polymsh"" but I'm not sure this is relevant. I've never had a model freeze upon exportation before so I don't really know that the problem is here.
Does the model have too high a polycount? The number of triangles is 20,408.
EDIT: Problem solved. I believe the model was to high poly for my computer. I reduced the poly count and it exported and works fine.
