Strange artefacts on model

Hi There,
New Cinema 4d user here with Octane plugin so sorry if this is a known thing but I'm not sure what to look for. Anyway, I downloaded a model from Turbosquid in C4d format and when I try to render it in Octane I get the attached weird artefacts. Anybody know what's causing this and how to fix it? I've applied a new octane material but that didn't fix it.

Many thanks
Roger

probably a scale issue!

try adjusting the rayepsilon in the kernel settings or chagning your scene size in c4d

ray epsilon. It's very similar parameter like that "view clipping" in C4D.

Np, welcome here. As Whersmy said, there is a relationship between objects/scene size and ray epsilon. Octane works on float-point math not double. This parameter helps when FP math is not enough.
