Hi, I have an issue with sharp faces when using daylight system (didn't noticed that when used HDRI map) — here is the simple scene with subdivided monkey model from Blender imported into Octane Standalone 1.20. I have noticed this when worked with more complex scene in Blender.
What am I doing wrong? )

Try to adjust "Ray Epsilon" to see if that helps.

Yes, that helps, but I'm getting an issue with Specular materials.

Yes, unfortunately that can happen when adjusting the "Ray Epsilon" and at the same time you have 2 surfaces very close to each other. A work around is to bring in the object scaled bigger until the problem goes away, or adjust the mesh (move the eye a little).
