Create a PxrOSL VOP Node (note the operator name is pxrosl:2 to avoid clashing with the node shipped with Houdini).
File Path for the oso. Parameters and inputs loaded from this oso
Source File Path for the osl. Will be compiled to File Path
Compose osl in code block.
Set RMAN_SHADERPATH environment variable to load oso files in path. These will be organized in TAB menu based on directory levels where they are saved.
Set environment variable RFH_ARGS2HDA=1 to create houdini digital assets on start up based on .args or .oso files found in RMAN_SHADERPATH and/or RMAN_RIXPLUGINPATH.
.oso shaders found in $RMAN_SHADERPATH are automatically converted to otls, and stored in $HOUDINI_USER_PREF_DIR/otls/rfh_osllib.hda
