Render curves as tubes?


Recommended Posts

Hi all,
I was wondering if I was missing something when it comes to render curves as tubes. I know that if you have a curve, you can set it's width attribtue and that will make it render as a strip. Then, using a hairNormal shader you can make it appear as a tube…ish. However, this is only a shader effect, so when it comes to rendering displacements on the tube, things can look pretty odd.
It is possible to render points as spheres, complete with actual geometry that can be displaced properly…but is this not possible with curves?
