Triangles on a large scale meshes

[litesound]

I'm just beginning using the Octane and I faced some problems - triangles appear across the surface of the mesh that becomes even more obvious on a large-scale scene. Even if I make the mesh denser, let's say 100 times denser, the triangles don't go anywhere - they only become smaller. The same happens if I crank up OpenSUBD Subdivision level to 2-3 and even 5. Normals on the mesh - no help.
Why doest that happen and what can I do to solve it?

Have you tried to adjust the ray epsilon parameter in the kernel node?

Thanks,
