Green-Man Posted May 12, 2014 Share Posted May 12, 2014 Take a look at the categories workflow. Basically, you are attaching categories on the objects (may think of them like tags). And then define Shadow Selection (shadowcategories) parameter on the light to control objects to cast shadows. May read about that in docs: http://www.sidefx.com/docs/houdini13.0/render/lights#categories Quote Link to comment Share on other sites More sharing options...
