Pyro sim Redshift Render Looks Foggy

[pizola]

Hello again Guys.

So recentrly (3 hours ago) I swapped to RS because my Mantra render was taking over 2 hours per frame. I started shading everything and had some problems with the volumes (Which worked in mantra perfectly fine)

Scene View

 

IPR with an area RS light with contribution set to .5 (to test)

The setup

 

As always, Thank you guys

From your top screenshot, it looks like you just want to render the VDB volumes, correct?  If so, then you don't need to enable the Environment option in the Redshift settings, this is a global volume, and isn't required to render VDB volumes.  Just ensure you have a volume shader applied to the VDB, and that Volume Scale is set to 1 for any lights that you want to affect the volume.

From there, adjust the density scatter and absorption scales of the shader to dial-in the look of the volumes. And if you want, under the Advanced section, you can set the shadow density higher which sometimes helps with shaping the volumes.

You were right. I am glad you answered
