Hello,
How can i apply a random color, from a fixed set of colors, to a multi sub material?
In detail, i'm using TyFlow to Birth a reference shape.
That shape has a Multi/Sub-Object material applied to it, and the diffuse color of one of those sub-materials is randomly chosen from a pool of 10 fixed colors.
With Arnold, i can use the "Object ID" and "1 of N color" maps to achieve that on a group of shapes, but i can't do it with a single TyFlow object, because i don't have an "Object ID" for each particle.
I also can't seem to do it using the "Material ID" operator, because then, each particle gets assigned only one of the Sub-Materials.
Is there any way i can pass an unique particle id or attribute to use in Arnold as User Data?
Any help would be greatly appreciated.
Thank you
