Scripting,  Maya

Set and load Renderer at Startup

Set and load Renderer at Startup

Now and then Maya forgets to load “mental ray”. To avoid the hassle of having to manually load the plugin, I wrote a simple script that is executed by the (Maya searches and executes this file when Maya starts).

Step 1

First, create a file at following location: * Windows: :\Documents and Settings\\My Documents\maya\\scripts * Mac OS X: ~/Library/Preferences/Autodesk/maya//scripts * Linux: ~/maya//scripts

Step 2

Copy and paste this script

import maya.cmds as cmds def loadRenderPlugin(plugin = ‘Mayatomr’, name=‘mentalRay’): if not cmds.pluginInfo(plugin, q=True, loaded=True): cmds.loadPlugin(plugin) cmds.pluginInfo(plugin, edit=True, autoload=True) cmds.setAttr(‘defaultRenderGlobals.currentRenderer’, name, type=‘string’) print (’# Result: %s Plugin loaded #’ % name)

Step 3

Now you have to add at the end of the file a line of code that loads the Render you are using. By default, Mental Ray will be loaded. However, you also can define a different function to load the renderer you are using like Arnold.

# Mental Ray maya.utils.executeDeferred(‘loadRenderPlugin()‘)

# Solid Angle Arnold maya.utils.executeDeferred(‘loadRenderPlugin(“mtoa”, “arnold”)‘)
