Hi everyone.
I was wondering if any had any information on a small problem I've run into.
I'm working with some really big landscapes (10km square or so). If my geometry is at real-world scale, octane seems to render with some artefacts. They look like slight tearing / phong angle errors.
Has anyone else run into this? Is there a solution?
It's no big deal if not, as the artefacts go if I reduce the size of the geometry, but still, it'd be nicer to be working with real world scale if possible!
Would appreciate any advice.
Thanks!

Hi,
you have to rise the ray epsilon value in the kernel setting to match the bigger scale

Hey,
awesome, that seems to fix it perfect! Thanks so much! I always wondered what that setting was for!
Is it the best idea with that setting to keep the value as low as possible, without getting those artefacts?
Thanks so much for your help!
