Hello,

When you render nurbs curves in mantra, they have a s parametric coordinate, 0-1, going from the start to the end of the curve. However, the value of the t coordinate seems to always be 0. I believe in RenderMan, curves have a t-coordinate going from 0-1 across the width, handy for faking normals, among other things. Does such a thing exist in mantra?

Thanks,

Jeremy.

Render/Dicing Tab of an object:

Shade curves as surfaces
When rendering a curve, turns the curve into a surface and dices the surface, running the surface shader on multiple points across the surface. This may be useful when the curves become curved surfaces, but is less efficient. The default is to simply run the shader on the points of the curve and duplicate those shaded points across the created surface.

Brilliant, thank you!
