We are using the .x file format. But when I export this model from XSI the UV coordinates are messed up except some parts.
Before I started unwrapping I divided my model into pieces with the "extract polygons(delete)" command. After unwrapping, I used the "Merge" command. After that, I arranged my separate UV pieces to fit the shape of a square for stamping. Is there anything missing or wrong in my workflow? This situation doesn't happen to other models of mine. Here's a picture of the problem(the model changed very little between the screenshots but the problem is still present):

Thanks a lot for looking [img]/images/graemlins/grin.gif[/img]

The only thing that i can think of is that somehow the uvs got rotated in either the export or the import. I would try rotating the texture ps. check all angles to see if that was it.

UV's normally begin in the lower left corner in XSI. For the directX specs, it begins on the upperleft corner. Try mirroring your uv's vertically before exporting.

Thank you both a lot. Mirroring uv's vertically solved the problem.
