Can you please tell me a little more about how you created the sweater.

In the group line there are two tab spaces whereas the normal is to just have one single space.

You appear to have four times the number of texture vertices than needed. I did a simple remapping in UVMapper and that brought the number down to an amount similar to the number of vertices in the model which is what I would expect. (Planar Z split front and back).

What application did you use to create and UV map the model?

I can create conforming clothing using my revised version of your model, although there are still some aspects that I would like to check pending your reply.

Many thanks,

Phil
