Launching VRay RT from an Scripted Button (Python)

[eibriel]

[Maya 2012 64Bits, V-Ray for Maya 2.0 Beta 2, Windows7 64Bits]
How can I launch VRay RT from a button? Its always return an error:

# Error: TypeError: file C:\Program Files\Autodesk\Maya2012\Python\lib\site-packages\maya\app\commands.py line 17: Object  is invalid #

Here is the code with several tries:

import maya.cmds as cmds

def launchRTRender(*args):
    print "launchRTRender"
    
    cmds.eval ("renderIntoNewWindow iprRender;") #Try 1
    
    #cmds.eval ("RedoPreviousIPR;") #Try 2
    
    #comrt = 'vrayStartIprRender "%s" %d %d "%s"' % ('renderView', 640, 480, "persp" ) #Try 3
    #cmds.eval (comrt) #Try 3
    
    #cmds.showWindow('MayaWindow') #Try 4
    #cmds.setParent('MayaWindow') #Try 4
    #cmds.eval ("IPRRenderIntoNewWindow;") #Try 4
    
cmds.window()
cmds.columnLayout()
cmds.button(label='RT Render', c=launchRTRender)
cmds.showWindow()

Thanks!!!!

Hi,

IPRRenderIntoNewWindow is a mel function, so you need to use maya.mel.eval("IPRRenderIntoNewWindow;") instead of maya.cmds.eval("...").
I've tried it an it works like a charm.
