In the scenes .zip file in the other post you have the "008-instancingCdColor.hipnc" that is an example using instances, not Octane sphere particles.

No color render. In your url you dont use a Instance example but a built-in octane sphere scattering. Any recommendation about the setup ?

I tried to add @alpha data in point with in material a NT_TEX_INSTANCE_COLOR instance with alpha4k_map.ppm file, no success, any idea to use it ?
thanks

My sim is around 10m grains and when i try copy to points (even if not visible in viewport and packed prims) H lags a lot and Octane cannot even start.
Is there a solution for this? I was expecting under particles besides "render as spheres" to be able to have a "geometry" option where we point to various sop paths. I tried also octane scatter its not working on grains and in any type of points for that matter unless a polygonal surface.
Please let me know what is possible.
