Arnold Maya 2017 not working

[darkmatter556]

i cant use Arnold for Maya 2017, im getting this error 

# Error: AttributeError: file D:\AutoDesk\Maya2017\Python\lib\site-packages\pymel\core\nodetypes.py line 409: nt.Unknown(u'defaultArnoldRenderOptions') has no attribute or method named 'drivers'

ive updated Arnold to 1.4.0 and im still getting the exact same error. ive looked around and havnt seen the same error yet, similar ones, but not this one. 

any ideas?

Hi

Does this happen at startup, or when you load a specific scene?

It looks like a scene-specific problem. The defaultArnoldRenderOptions node in that scene is broken.

I expect there was a lot more logged in the script history.


First, try this:
- Restart Maya
- Open the Arnold Render Settings. That creates a defaultArnoldRenderOptions node.
- Try again to open the scene

If you still get the same errors, then do you have these four nodes in the scene?

- defaultArnoldRenderOptions
- defaultArnoldDriver
- defaultArnoldFilter
- defaultArnoldDisplayDriver

You can check in the Outliner, just clear Display > DAG Objects Only

If so, then try this:

- close the Render Settings dialog
- delete those four nodes
- save the scene (with a new name)
- restart Maya
- load the scene you just saved

it seems to be only with this scene, i have Arnold, but i keep getting that same error when i try using it.

when i open the outliner, i do not have those nodes and i have tried the steps you suggested.  

here is the script report

Hi

Are you sure you don't have a defaultArnoldRenderOptions node? 

You can create it with this Python snippet

from mtoa.core import createOptions
createOptions()

Can you strip down the scene (remove all the geometry and shaders and textures)? The scene should still have the same problem with the render options, and you can post the simplified scene here.
