is there any way to transfer color from particles to cloud?

[Anatol]

Hi guys. I found pretty good topic explaining how to transfer color to volume from particles

http://forums.odforce.net/topic/19328-get-pyro-color-from-particles

 

But I cant rebuild this for using with cloud rig. Is there any way to transfer color from points to clouds?

Thank you.

I also tried to use AttributeVop to set the color of volume. Cd sets entire color of the volume, and I can't get how can I use points to set the color of volume

You need to create vector (3 float) volume where you store your colors (e.x. Cd) or three float volumes (Cd.x Cd.y, Cd.z). e.g. Volume From Attribute.

Then in your VolumeVisualization set Density Field to density and Diffuse Field to Cd if you have vector volume (or Cd.* if you have 3 floating volumes) and keep Diffuse Ramp at defaults.

Thank you pezetko. I tried to use attribute from volume, but I still got no idea how to transfer color to cloud rig cloud - it's already created volume with it's attributes?

Almost there, just merge Cd volume with the Cloud volume.

See file (visualization in the viewport is somehow wrong on my system, but render is ok)
