point instance procedural material sop override point color ?

[Doum]

Hey all,

 

I hope someone can shed some light on this.

 

I have to emit a tonne of particles, more than 20 millions, and instance geometry on them. the bottleneck come when I try to override the color of the instances with the Cd attributes of each points.

 

I would like to ear from you that there is a better way to do this than to use a material sop because it's taking so much time to compute before rendering.

 

Any advice is welcome!

 

Here a sample scn

Thanks in advance !
