weird artifacts on far away surfaces

[Rik56]

Hi, I have a model of a building, I set up basic materials with diffuse shader with diffuse and bump map. However when I zoom away I see some strange artifacts.

This is a close up of the ceiling:



And here it is from far away:



This is the material setup:



Any ideas?

To remove those artifacts you need to adjust the scale of the object so it matches real world values.
If you can't adjust scale increase or decrease "Ray epsilon" value in kernel settings.

Yeah, scaling is not an option but the ray epsilon worked, thanks!
