controlling source property fog_denisty with a procedural noise?

I wish to control the fog density emission with a  procedural noise and NOT a color set.   how might i go about this?

very cool, thanks man.   I cant tell from the image how you were able to visualize the texture in colors however.

 

Also I was wondering as an additional question, is there a way to use regular maya procedural noises as density emitters? 

 

Thanks,

 

Mike

Hello @mikeporetti 

 

The best way right now to break-up fog_density and other properties on the source, is through the "vary_source_property" node, which can randomize values over the input mesh vertices, and/or reference CPV maps from Maya.  

 

You can also try more creative approaches such as the one shown by @suryamunny.

 

We plan to continue developing this workflow by providing more procedural methods to break up values at sourcing time. 

 

Thanks!
Kosta
