is it possible to exprot the uv map

i was wondering if its possible to export an empty uv map of ur model,and then texture it with another program,and then import it again.

Yes.
Its in the UV menu. Its called Save UV Layout

it works,but it saves in a format that i can open with any program.is it possible to change the format?

what os do you use? If you use Windows or Linux or… dont even know hw many os`s are supported by the gimp… anyway, why dont you download the gimp?
