Tag: ubershader blockers


In Renderman Advanced they explain how to use system co-ordinate blockers. In filmmaking the lighting guys will often use boards to block off light.
This is very simple.
1. Under 3delight menu, Add Coordinate system.
2. put the name eg ‘delightCoordinateSystemShape1’ into the ‘blockercoords’ section of the
uberlight shader
3. Move co-ordinate system into place. Adjust blocker settings in uberlight.
