Hello,

I need quick help. In shader I want to test if point is in certain group. There is In Group node but it takes input parameter Geometry file. In vopsop I could set it to op:/obj/path/to/object but what expression should I write there to set it to shaded object?

 

Thanks.

I don't think you can reference geometry via an expression in shaders.  You have to write it to disk and specify a file path like $HIP/geo/test_group_$F.bgeo.  Mantra is a separate program from Houdini, so it cannot access a certain sop's cached geo
