I want to edit some of the .msh models, but I can't use XSI, and since this is my work comp, I can only have SketchUp on here, is there any way to make that conversion?

EDIT: Oops, I accidentally posted on the wrong forum, can someone move this please?

I don't think so...

I doubt it without actually having XSI. You'd probably need some like MeshTool, but for .dae or .skp instead of .obj.

yeah, is it possible to do that?

i pretty shure you can get objs into scetchiup since the pro version has an obj exporter (convert the mesh with meshtool to obj)
bzut sketchup works different from XSI (i dont know how) which makes it difficult to make a model that battlefront can use (i once tried to convert a sketchup bolter to battlefront, it had so many polys that some parts would never have shown up ingame)
