I have an alembic named light_geothat has pathattribute in it which are the geos it contains. I'd like to use specific geos(path) from this as a mesh light which would get plugged into "Geometry Object" parameter on the light. However, this parameter reads the whole object (e.g. ../light_geo). Is there any way to exclude parts of it in the same parameter via an expression? I can of course use a blast node and remove path primitives but I'd rather do it all in the Geometry Object parameter.
