For each object to get a different variation, you need to select something unique about them to create a unique seed. You have a choice between the object's id and the object's name.
These attributes are created by the software outputing outputting the RIB and depending on your host, one may work better than the other.- 0:

Seed
When set to zero, all PxrMultiTexture patterns using the same manifold will compute the same random seed. If you want one of these patterns to compute a different variation, set the randomSeed to a non-zero value:| *RIB*: ``float randomSeed``
