SOP to LOP - instancing geo according to specific attrib val April 6, 2020, 11:36 p.m.

Look at the prototypes section at the bottom of the Instancer LOP's parameters; you can set the prototypes to come from the 2nd input, and use an attribute to identify the prototypes by name. []

Hope that helps!

I haven't tried, but I would suspect the Render Geometry Settings would be the place to look?

Working with Variants and LODs Feb. 26, 2020, 9:15 p.m.

Nope variantSets don't intrinsically have a concept of “LOD”, though they can be used for that. That HDA in LOPs is just an example setup; maybe SESI have plans for something that looks for LOD-prefixed variants in a given variantSet?

USD has some other mechanisms for LOD, such as Purpose and Draw Mode. As VariantSets can't be animated over time, they couldn't work for any dynamic LOD conventions.

Hope that helps!
