Cloud Light real scale

Recommended Posts

Hey guys,


I am trying to generate clouds in real scale with the Cloud FX Tools and I'm experiencing problems with the Cloud Light SOP.
All the tutorials show clouds in a scale of a few meters, but actual clouds are kilometers big (small cumuls clouds). In this scale the Cloud Light SOP produces strange results. The speed field is inverted and the light field is completely blurred.


Does anyone know, how to set up or modify the Cloud Light SOP to work correctly in this scale?

I've found The Cloud Light rig very slow and not working well with animated cloud.

You can cheat that by diving inside the CVEX where the clouds are generated, remap the noise from 0 to 1 or use the final density plugged into a ramp or spline VOP, create as many colors as you want and export it as Ce (color emission).

The cloud shader picks up that Ce and generate the emission for you.

Thank you, Dobril.

 

I don't quite understand how to get a scattering-like effect by just remapping the density. Would you mind sharing an example scene?
