Random hatch in rendered image


I’m wondering if anyone’s familiar with the type of parallel lines appearing in the lower part of the image attached? This issue occurs whenever I try to render at a portrait ratio, meaning that I set the dimensions to exceed the current viewport. I’ve tried rendering using the same image ratio on different models, with our without texture, but to no avail. I’m using Rhino 6 for Mac.

Thanks in advance!

Hi @b.ronngren, late reply but if you still have this issue, can you post a simple 3dm file with the dimensions you’re trying to render at? I’ll take a look.
