Arnold, problem running under maya.standalone

python

#1

I have tested this with both maya 2014(mtoa, 1.0.01) and maya 2015(mtoa, 1.2.xx)

after you have a regular install of maya and mtoa.
open mayapy for example in C:\Program Files\Autodesk\Maya2015\bin\mayapy.exe

import maya.standalone
maya.standalone.initialize()
import maya.cmds as cmds
cmds.loadPlugin(all=1)#this loads all your plug-ins

and then every other plugins loads fine, except for arnold, which will give an error similar to:

well, every version will look slightly different, but it’ll always involve PxMayaNode.cpp and xgen loading problem.

I’ve tried with quite a few versions, in 5 or more computers with very different configurations, and always fails, if anyone can succeed, I would loved to know your config, and software version and exactly how you did it. Thanks in advanced!


#2

does xgen load properly?


#3

I’ve tried in 2015, and nope, it doesn’t, xgen also doesn’t load properly, but in 2014, there’s no xgen that came with it, so I can’t try it, but of course, in GUI mode everything loads fine, so I’m thinking maybe it had something to do with some preload script in Gui mode that’s missing from standalone?


#4

Actually, xgen loads fine, although it did gave some error about Unable to execute igInitialize.mel.Unable to execute xgen.mel.Error: file: C:/Program Files/Autodesk/Maya2015/plug-ins/xgen/scripts/igInitialize.mel line 63: not found,

but I was able to fix that by adding that to path.

now xgen loads perfectly, and yet, arnold still doesn’t load, here’s the error for arnold even after xgen is loaded:

>>> cmds.loadPlugin('xgenToolkit')
[u'xgenToolkit']
>>> cmds.loadPlugin('mtoa')

#5

I have figured it out~
just by adding

sys.path.append(‘C:/solidangle/mtoadeploy/2015/scripts’)

will let arnold load up, while the error about xgen is still there, it was able to load a maya scene with arnold nodes.


#6

and after I installed the latest maya 2015 extension 5, it crashed right after loaded… like such:

#7

So it doesn’t take path in Window’s variables or Maya.env into consideration?


#8

I’m guessing it does, I just don’t know the correct one to add in.


#9

That error looks like a mismatch between the compiled plugin and the new maya. C++ wins again


#10

but in Gui mode it works fine.
