Some Help with the clouds

[houourin]

Hi there I'm testing the volume grid with some OSL noise maps for cloud generation.
So far so god! but I can figure out how to render animation with the "Volume Light Cache" activated ( even at 0.0 value ) it just flickers and flickers and flickers... and I'm a bit out of ideas.

I've been reading the documentation about it, I know is not related to the other Light cache...
Deactivating it might solve the problem but the times grow a lot.
Tried also playing with the Min shading rate... but not lucky with that either.

Also I'm unable to use the same setup with the OSL Uber Noise in VrayGPU, I'm not so used to VrayGPU so I guess is not entirely compatible with some of the OSL maps? not sure about this one thoug...


I would really like some advice on things I could try, or maybe confirmation that for animation is impossible to use the Volume Light Cache

Ok I found another page in the documentation about In depth Volume rendering... and there is better explained that... I'm screwed

I wonder if there is more ways to improve the speed thoug or if you guys recommend GPU render for volumetrics
