Hello, how can I add a noise into an eviroment fog in Vray 6? I tried out a lot, but… I take an Envirement Fog with a cube subordinate (creating a steam) - i tried to create a noise in every folder. 
Please tell me the right workflow! Does it work with c4d shaders? Thanks, Harry
Hello @HarrySeidl ,
It is possible to add noise to the Environment Fog in V-Ray 6. Please check if you have assigned a Material to the Material Tag. It contains the UV Mapping information which is needed for the Noise.
That’s it - wonderful!!! Thanks @viktor_angelov
