Ray Epsilon ?

[sagun]

Hi,
What is ray epsilon doing in these 2 renders ? I am experimenting with DL (GI_Diffuse) and have spec detph 12 and glossy depth 4 setup.

*Attached.

Is the ray epsilon changing the IOR ?
settings: rayepsilon 0.001 and 0.1 respectively

Hi sagun,
in short, it depends from the scene scale, and it defines the precision of the render.
Please, have a look at this more detailed answer from abstrax:
