Assign materials w probability [SOLVED]

[starion83]

Hi everyone,

I'm trying to assign materials to a set of objects (each with a unique name attrib). But instead of randomly applying materials, I'd like to weight the application of materials, so that for example 10% have mat1, 40% have mat2 and 40% have mat3.

My first thought is using for each piece + vex with if else for weightings? Or is there an easier way I'm not aware of?

Thanks in advance!

Looks like what I was missing is the assignment of material path. with s@shop_materialpath = "....";

A weighting of 10% / 90% can be achieved by looping over objects with vex:

if(rand(@class) < 0.1)
    s@shop_materialpath = "/mat/Test1";
else
    s@shop_materialpath = "/mat/Test2";

you can also use Attribute Randomize in Custom Discrete mode of String type to create shop_materialpath attribute, it will allow you to specify weight for each string value

and put class in Options/Seed Attribute parameter

Thank you Tomas! I'll give this a try
