Hi JD! Continuing from https://discourse.mcneel.com/t/ground-plane-bug/108918… I had an additional problem with Bella as the current renderer (IPR in the viewport). The texture mapping seems off – I can see the individual pixels in the ground plane. The problem doesn’t occur when using “raytraced.”
I’ve added support for this now. Until I get a build with this uploaded, you should be able to use the mapping controls in your ground plane material (in the texture), instead of the extra ones they have in the ground plane settings.
