Thank you for the reply again David. Update on my issue. I think I'm doing something weird with using the "Extra Vray Attributes", "Per-particle attribute export" (RGB and Opacity).

So below is an example of what I was trying to do-

Apply the Per-Particle attribute export (vray) to my particle shape to get the information-


Then go into my hypershade and use a particleSamplerInfo node to push what I thought were those values to the material I had applied to the particles-



What I think I NEED to do (just sort of realized this tonight), is use the correct outputs on my particle shape node-


However, plugging the "Vray PPExport Opacity" and the "Vray PPExport RGB" right into the material I've applied to the particles did nothing (as where using the particle sampler node sort of worked unless I was doing an animation in which case it failed).

So revised question. How do I use the Vray PPExports to drive my material? I feel like I'm getting closer at least.

Thanks all.


Edit: I guess the ParticleSamplerNode is the correct way to go about this...
Straight from the documentation-


Will pick up on this tomorrow night after work again.
