Vray Environment fog speed

[CG_Utopian]

Hello everyone,

I am having an issue with vray environment fog. once i use a map in the density slot the rendering speed of the fog drops substantially. is this something we have to live with or is there a fix that i am not aware of? Thank you

Increasing the raymarching step size will help. If the map is a procedural map, you may try to reduce the fractal levels; if it's the 3ds Max Noise map, you might want to consider a faster alternative like Bercon Noise (I think there was a faster Blur noise texture too).

Best regards,
Vlado
