White grid of dots

[JoshuaBastiaans]

I was making a landscape/forest ish scene but when I tried to render it out it gave me this white grid of dots. I don't think I did this deliberately. So if you know how to disable this please help. I'm creating the scene with forester and rendering with octane.

Kan het soms zijn dat je "Atom Array" hebt gebruikt? (zie plaatje).

When objects don't show up in Octane it often works when you put a Octane tag on the object in the object manager, I only used Forester with Octane once and remember they didn't work well together. I believe I had to expand the Forester objects to actual geometry in the end..
