Hi,

I'm encountering an issue with Arnold in Solaris.
As you can see in the attached picture, the curvature node doesn't work properly when using CPU mode.

Only Curvature_Convex returns nothing.

Has anyone else experienced similar behavior?
I have attached the .hiplc file link for the reference.

If someone could take a look at it, I would greatly appreciate it.



Thanks,
Kensho

Hello, this seems to be happening because USD meshes aren't double sided by default.
Try adding a mesh edit LOP and enable double-sided and it should fix the issue.
