Hi, i'm trying to render line in mantra so that edges are transparent, and use the ‘free’ space for rotating line a tiny bit. But for some reason the shadow is pointing in the wrong direction.

If you look the attached image, there is a line where edges are treated as transparent. The line is ‘rotated’ (= controlling what part of the uv space is the center) to left. Now, i would assume that the shadow would be rotated to left also…

I'm missing something but what.

Cheers
