Re:Strange effect using volume, CPU BiDir

Yes, and as you can see, beam above spot of second spot light is not visible.
It seems for me, light passing homogenous, scattering volume keeps scattering outside the volume.

Re: Strange effect using volume, CPU BiDir

Hi B.Y.O.B. Thanks for the answers and the tips. I did not know how important setting of external and internal volume is. The gap was intended. But good to know that overlapping is the correct solution. Also setting priority for volumes is rather new to me. "by the way, the bottom of the glass looks...

Strange effect using volume, CPU BiDir

Today, I tried to setup a simple scence with a glass of wine. But no matter which glass property I changed I was not confident with the result. In the last setup I noticed a scattered beam above the glass. I miss specular reflections too. What is wrong with this scene and objects? Glass of Wine with...

Test scences GPU Path vs CPU BiDir

It seems this means scences based on materials like matte or mirror. But as soon as glossy or metal with roughness is ...
