OSL Shaders

In your custom RenderMan_for_Maya.ini filerfm.json file, you can specify a location for OSL shaders under the preference: RISOSLSearchPath

Node IDs for Patterns are embedded in the metadata. Below is an example from the PxrLayer OSL shader.

C++ Plug-ins

In your custom RenderMan_for_Maya.ini rfm.json file, you can load your .args files like the below example, where /path/to... is your path to the stored .args files followed by the name of the args file:

LoadExtension args "/path/to/args/foo.args"

In your custom RMSWorkspace.ini, you need to make sure it has the correct location to load and use the plug in. Replace /path/to/custom/shaders with your location.

SetPref WSSearchPaths.rixplugin [list \\\${RMSTREE}/lib/shaders/ /path/to/custom/shaders @]

            "nodes": {
                "search_paths": [
                    "${RMANTREE}/lib/plugins/Args",
                    "${RMANTREE}/lib/shaders",
                    "${RFMTREE}/lib/plugins/Args",
                    "${RFMTREE}/nodes",
                    "${RFMTREE}/test_files"

Node IDs for these are included in the .args file. The order doesn't matter but it must be in the first level of the tags. The below example is for a light.
