Hey guys, 

i painted colors in several vertex paint modifiers, each with a different map channel, and i would like to throw those colors into a composite material and blend some together. 

I also painted a vertex paint modifier for the distribution / hair denisyt, and this work fine. No issue.

Somehow I don't manage to retrieve those vertex color info in the diffuse color of my Redshift Hair material. Any tutorial or link that could help with the process please? 

Thanks.

A.
