I found the property primvars:karmabject:tracesets inside the render geometry settings node, but how to make it exclude other parts of the usd hierarchy from being visible in reflections/refractions?
Could not find any documentation on it anywhere in the help.
Hi. karma “traceset” parameter is currently only used internally for shadow linking. It should be hidden from user in the near future. Visibility toggle for reflections/refractions is currently unsupported but will be done via raymasks instead.
