Light linking can be done with the Light Linker node. Simply drag lights or collections of lights to the center Rules section. Then drag geometry to the on/off sections for each light. Similarly, you can drag geometry into the Rules section and add lights to the on/off sections for the geometry.
Differences from RfH
Light shapes are visible to the camera by default. In order to turn off the visibility on all lights, create a Render Geometry Settings node and set the Primitives scope to "All Light Primitives". Then uncheck the Camera Visibility setting.
Solaris does not have a texture manager. To use a texture on a light source, you must first use txmake to convert the files to .tex
Known Limitations
A number of lighting features aren't supported yet within Solaris:
- RenderMan doesn't have a point light type, so the point light type on the node is translated as a sphere light.
- Light plugins that aren't part of the USDLuxLight schema - PxrEnvDayLight, PxrAovLight, custom light plugins
- PxrMeshLight
- PxrPortalLight
- Light Filters
