The user experience in RfK 22 is very similar to what was available in RfK 21, but there are some changes that are necessary to transition.

Light Filters

The PrmanLightFilterCreate macro has also been removed. It reads in args files for use with any light filters found on the $RMAN_RIXPLUGINPATH and can share light filters between lights. In Katana 2.6 and newer, you can create light filters directly in GafferThree.

PrmanGlobalStatements and PrmanObjectStatements

PrmanGlobalStatements and PrmanObjectStatements have been reorganized. This will allow future upgrades to PRMan options and attributes to happen seamlessly under the hood without breaking compatibility.

Environment Variables

The default RfK KATANA_RESOURCES location has changed in 22.  Now the default install location is (Linux): /opt/pixar/RenderManForKatana-22.0-katana2.6/plugins/Resources/PRMan22.
