For hair/fur curves: To use the IGS/Interactive Xgen surface UVs for color/texture, you can reference this in the PxrManifold2D of your color placement as scalpS and scalpT Primvars. |
For flat, ribbon style curves, the curve needs to be supplied with normals. Maya doesn't have this functionality out of the box, so there's a RenderMan-centric way of accomplishing this via primvars.
- Select the curve's shape node (select the curve in the outliner and press the down arrow).
- Add a RenderMan primvar named rmanNN
- main menu > Modify
- Add Attribute...
- Long Name = rmanNN
- data Type = Vector
- Change rmanNN in the curve shape node to anything but 0, for example, 270, 1, 360.
- This will supply the curve with a normal and twist the curve.
