Hallo GoncaloP

if the Depth value in secondary bounces is the number of bounces, what is the oather value ?

4

does it affect also the irradiance map or only direct computation?

5

The other value, subdivisions determines the number of rays for secondary bounces, if you use example number like 20, means 20x20= 400 rays.

It affects also the irradiance map, but usualy, the number of rays for first diffuse bounces are enough, especialy in exterior scenes. In certain cases we need to use them too, especialy in interior scenes.

where can i control the number of rays in fist diffuse bounces?

8

Hemisphere subdivisions: 50x50= 2500 rays
