Strange polygon artifacts at distance

[GlenDeeplocal]

Hi, I just started using Octane in production and I'm having a problem with some polygons displaying weird patterns when the camera is at a certain distance from the camera.
You can see it in the image I've attached. It's making dark triangles and swirly patterns on the white wall in the back of the room. I can't seem to get rid of it. When the camera is close to the wall the artifacts do not show up.
Any help is appreciated!
You can see better what is going on in the first image with the spheres.

Thanks for no response. I figured it out. It was the scene scale options in the render settings. Not sure why the default settings would not be set for real world units.

You can also increase the Ray Epsilon in the render settings. I don't really know how all of this works but it fixes the problem as well

Ah yeah. Rayepsilon did it too. Thanks! That's a better solution.

Hi There,

the better solution is work on real word scale... as Maya 1 unit 1cm and then change on render settings scale to 0.01 This is the better solution is wrong if you changed the Rayepsilion because if you do some render based on reality will be complete off. also when you create scenes based on other render engine where is completely standard on the industry the workflow (1 maya unit=1cm) will be complete off.

I spend years telling the Guys the 1 maya unit= 1m is just not standard and no sens. but some people rendering planets was using this scale to work better with Maya but at same time is just change near and far plane on the camera.


Complicate. but the Rayepsilion I never touch to avoid weird results.

Best,
Jo
