attached pic is renderd with PBR
i don't know why it happen like this, even if i make Min Ray Sample to 4
Max Ray Sample to 12 and Noise Level to 0.01, the black pixel appears some frames also, maybe if the Ray Sample much bigger it will be nice, but the render time is much longer.
any solutions?

Those “NAN” artifacts shows also when I apply displacement through pyro shader and use any one of the mantra raytracing engines; I had play with the ray bias without luck.

thank you
ray bias not works for me too, i even decide to fix it with houdini comp.
but the nuke's solution is simple
i wish it can be fixed in houdini render
This is bad.
Can you post the .hip file so we can take a look and see what's causing this?
