i would like to be able to grab the primitive number and multiply for a random number, i want each of my primitive be different.
could make an attribute at sop level where:

@myprim_num = @primnum

but i don't want to store it as a attribute i think is unnecessary to add more data since is right there. any ideas? (hopefully works with materialsX)

Tanks guys

I'll usually generate a float from it. like:


(*you might need to promote to vertex)

But I dont know if @primnum can be used directly. What renderer are you using?

karma, i am just surprised that primnum or point num are not accessible by default and need to be store into the geometry.
