Hey all - using group SOPs connected to an imported fbx mesh containing house walls. Trying to pick north-facing, east-facing, etc groups for texture operations.
I can set up one group SOP node okay with 1,0,0 for the normal selection vector. But if I edit that to something like 0,0,1, or if I add a second groupSOP and set it to 0,0,1, it immediately hangs up the whole session very consistently.
