VRay Demo: Rendering nHair

#1

I’m trying out the V-Ray 3.1 for Maya demo and having a bit of trouble. I have a preconstructed scene that has nHair, but the nHair won’t render. I’ve tried both with and without applying a VRay Hair shader (as well as having those attributes enabled as well as disabled.) I’ve tried numerous other things to no avail.

The scant tutorials I can find on these matters indicate that I should just be able to render it as is. There are no indications that this is a limitation of the demo. I tried joining the Chaos Group Forums to ask about this issue, but they seem to be locked down such that I can’t post anything.

I have also tried creating a new scene using nHair, even just a small amount. I tried it using the same model as well as a separate attempt with just a plane and a sphere. The only thing I’ve managed to get working is a crude sample scene I found somewhere online. It is a sphere with nHair applied. It rendered in VRay with and without a VRay hair shader. However, if I create another sphere in the same scene and apply nHair to it, that new nHair will not render.

Any ideas?

I managed to figure it out. I was running up against the 200 objects limit of the demo. When I created the simple sphere’s nHair, the defaults put it over that limit. Rather than only render part of the nHair or something, the nHair is being entirely ignored. Hiding them also does not apparently stop them from counting against this limit.

I was able to successfully render the scene with a tiny fraction of the number of follicles the scene had.
