Is there a way to query the Solaris scene polygon count? I assume some level of render verbosity will spit out these things in the shell?

Or perhaps writing a usda to disk and parsing it?

That's not actually a perfectly well defined question, because it's not necessarily clear how to count instances, or point instances. But hou.LopNode.stagePrimStats gives you something that might be useful. It's the same information that shows up inthe window that pops up when you Ctrl-MMB click on a primitive in the scene graph tree and hit the "+" icon for more detailed information.

Thanks Mark, the + button actually gives me all the info I need. Thanks!
