Hi! I'm getting some artifacts in a very simple scene of some grids.
It's two area lights with samples in 4
A environmental light with samples at 4
Render quality 2
I have tried setting all samples up and down, changing the parameters of the grids for more mesh resolution, and always the same errors.

BTW, I am nacho, a very new user with Houdini Indie.

Great links, thanks!

I am trying to make it work Renderman in Houdini 18.0.348, I have downloaded the last prman 23.1 that comes with the pro server.

But it doesn't work. It gives me an error. “Unable to execute prman”.

The fail can be on the plugin side or the Houdini side, I don't know, but I have prman working in Maya without problem.

It's only for testing, I don't need prman in Houdini, I am learning Mantra. But It would be cool.
