Hello!

I have stumbled upon a problem where I am unable to render ribbons properly in Karma on H21.0559.
Karma CPU will not generate any uv when normal attribute is present and switching between flat ribbon and oriented ribbon does not make any difference. Ribbon always faces the camera.

Karma XPU generates rounded curves and also uv's. So the present N attribute works for generating uv's. but for some reason CPU does not.

Is there any sample file preset which would demonstrate the proper setup, perhaps I am missing something

For anyone trying to render oriented ribbons in Karma CPU. It works with B-Spline or Catmull-Rom. I did not see this mentioned in the documentation as a requirement.
