Hello,
I’m trying to achieve a light beam in the fog, as attached. Environment fog seems to work nicely and renders quickly, but as soon as I’m using a map to make the light ray more interesting, light cache takes ages to compute and the Rendering pass 0 jumps from seconds up to 7 minutes. With thoses render time I can’t imagine a whole scene and multiple lights. Any idea how I could optimize this and make it faster?
Thank you in advance for your help!
I wouldn´t use the Enviroment Fog for such dense light beams. Maybe I am wrong and also had no idea how work with that properly, but I found as well that it is slow like hell.
Using legacy Spotlights and using Atmosphere & Effects might make the run instead. That´s way faster.

@caypiranha I don’t understand your answer, as VrayEnvironmentFog **is **Atmosphere & effect rollout? Furthermore, EnvironmentFog works really fast without using a texture in the fogdensity slot, especially using it including the concerning light only. Can you elaborate on your solution please?
using “Atmosphere & Effects” Rollout on Light´s Attributs directly. Use “Free Spot”
You may also try to bake the procedural texture into pixels… as you might imagine, precudrals are hardly having a beginning and an end, wich makes calculation for the renderer slow ( if I interpret this technically right)
Alright, thank you I will try this! have a fantastic day 
…ditto! =)
Edit: please ignore.
