making color "stick to moving particles ...


Recommended Posts


I'm trying to replicate the way you can set color for a particle's "initial state" in a Maya particle system.

I've looked through docs, tuts, etc, and have not been able to get this to work:

Here's what I got so far:
I've scattered points over some terrain Geo,

used a point Vop to create noise based color for the Cd attribute on the points,

then used the points as the initial geometry in the popObject.

The idea is to have textured "dust" blow over the Geo (I'm driving the pop animation with a Pyro sim).  

The animation works well, but I can't figure out how to transfer the Cd attribute of the scattered points to the particles.

I played with creating the color with a PopVop in the Dop network, but the color is assigned by position so the particles animate but the color does not.


I've attached my test scene.

I'd appreciate any clues; thanks in advance :)
