thanks for the reply but unfortunately it seems to return a number from 0 to 7 that is the number of triangles in my example geometry. While the number of primitive sets is 4 in my example. But in fact I can use it at first to find the primitive set (knowing the size of each primitive set and its index). Then I have to verify if the "primitiveIndex" attribute of the same triangle changes moving that triangle from one primitive set to another.
