This is probably just for Lionel but maybe someone else can help also.
I am working on an image and in Blender it looks good. When I export to Octane I am getting some weird lines appearing in the render. It is as if the exported (1,17) is generating extra mesh from somewhere.
Lionel, if you want I can sent you the .blend if it will help.
