Hi Michael,

sorry again, I didn't realise that the rotation was actually 90 degree, I was just looking at the star and it wasn't pointing up and I jump to the conclusion that it rotated by some strange angle.

In the file (cleaned up) when looking at the seam, it starts at 0 degree and ends up at 90 degree. This is caused by the UVs orientation like you say.

Thanks,
Felix
