Useful Python Calls - (in progress)

return to main index

Some useful mel procs for adding primvars can be found in RfM: Customizing.

Introduction

I intend this page to become a library of useful python calls, and environment variables, for use with RfM 22.x. The code samples for this page has been obtained from the Pixar RenderMan forum.

Generating Ribs

import rfm2
rfm2.render.frame('-ribFile')

To Load a Specific Render Quality Preset

import maya.app.renderSetup.views.renderSetupPreferences as prefs
prefs.loadUserPreset("RenderMan_Draft")

To Find the Path to the .json Presets Files

import maya.app.renderSetup.model.renderSetupPreferences as model_prefs
print model_prefs.getUserPresetsDirectory()

To Set the Path to the .json Presets

In the maya.env file set the value of this environment variable.

Or, in the users .profile set the value of the environment variable.
