Problem with the UV coordinates for the skin of a new unit

[Duke John]

I edited very heavily an existing model until I got this:



Since the model was so altered I of course also edited the UV coordinates using UV unwrap. This is what I got:



I then selected the body and made it an editable mesh to get rid of the UV unwrap modifier in the stack. I assigned all the vertices to different bones. Then I exported the model.

I imported the CAS file to see if everything worked and it didn't. It somehow keeps forgetting that I have altered the UV coordinates. The CAS model looks like this:


When I unwrap the UV I get the following:

Exactly is how it looked like in the original model so it "forgot" to use the new UV coordinates.

I also tested with keeping the unwrap modifier in the stack (thus not collapsing it), but that doesn't help either. I know that some of us have edited the UV coordinates without problems, but what am I forgetting?

Edit: after reading the CAS editor readme I broke all vertices in the UV editor. Collapsed the stack, made a new skin, exported, and still it's showing up correctly.

Please help since that is the last hindrance before I completely understand the process.

Thanks,
