Good day community, I have been in Houdini for a short time, and the truth is that I only use it for small basic animations, but yesterday I made a static image and I wanted to render it in mantra. There you can see those squares that didn't render well. As I don't know much about rendering engines, I don't know how to find out (or find it here in the forum) what is causing this problem in the final rendering result, if it is an option I clicked wrong or if it is my own (poorly) machine.

Thanks and sorry for the newbie.
