PointInstancer and Light Linking March 3, 2021, 2:33 a.m.
This is actually something on the Redshift side. I've posted about it on the Redshift forums. Karma seems to produce the expected results. Thank you.

I'm having some trouble with light linking on pointInstancer. Should the link be made on the prototypes or the pointInstancer primitive? Every combination I've tried is producing results I cannot fully understand so I thought I'd ask what the recommended procedure is or if this is something that is not supported by USD.
Thank you.
Thank you.

I'm not sure about vex but you can easily get anything with a python node and the pxr USD API. For example
There is already a stage variable when you create a python lop which is the conne ted stage so you can possibly skip the whole Usd.Open() line.
I might have syntax errors but hope it paints a picture. Documentation for the USD python API is a bit tricky but it's worth looking into it.
from pxr import Usd
stage = Usd.Stage.Open(<usd file path>)
unitscale = stage.GetMetadata("metersPerUnit")
