usd model variants from attribute

[sixjames1000 0]

Hi all

 

I've been looking at creating usd variants from the following, thinking on using this to create a model with variants from a piece of geometry that has a primitive attribute called "myattr" with 2 values (say half a sphere with myattr="left", and the other side called "right")

1- sopimport an object into LOPS with prim attributes.
2- create an add variant to existing primitive block
3- done

Any ideas on how to iterate through each of the primitive attribute values to create this variants? 

 

adding a hip file for reference, maybe someone can help

Thanks in advance!
