One step forward. One step back.
I downloaded AC3D again and used the include premade shapes. Well, success: the cube works now. It seems that the version i got from that more then once in this forum referred to blog is not ok.
Happy with this i tried a fast one (see in picture) and imported it into SL. And again: all broken.
But! As you might see on the picture, my uv-map seems not to be closed. Is that so? Are these gray areas what everyone refers to when speaking of "holes in the uv-map"?
And if it is so: how to close them? Just by choosing vertex-view and moving as many vertecies whereever i like to cover the gray parts?
