New to Arnold 2017 and I have some questions

[Anonymous]

Hi guys!

I am new to Maya 2017 and Arnold. I have some questions. Firstly, how do I update maya? I still dont have the Arnold Material Presets and I dont know how to install them. Thank you in advance!

Well Maya is updated through your Autodesk Account or the Autodesk web site (but it depends on if the update is subscription based or a normal update that everybody gets).  However if you are a student using the free version, there are known issues about students not being able to see or install any updates (and Autodesk is working on it).  Secondly is this Maya for Windows or Maya for OS?

If its Maya for OS, its not an update, its a complete new install.  In the end I'm not a Maya and Arnold user and I have no clue about missing Arnold Material presets.  Although you are asking installation questions, you may get a better responses/solution/answer by asking this question over in the Maya forum.   Good luck.

Hello @Anonymous,

Welcome back. 

This is correct you can also make sure you do not already have it installed. Make sure it installed "mtoa.mll" in the Control Panel (you can try repair) & check within the program. Please review this article: Arnold is not showing up as renderer in Maya 2017

I will move this post for more feedback.

Thanks for your reply. I have Arnold installed and loaded. I have no problems with rendering or using its materials. Its just, the aiStandard doesnt have presets. I have the student version.

Thanks for your reply. I am currently using student version on OS. Maybe thats the problem.

No, that doesn't matter.

What version of Maya and what version of MtoA?

The presets were added in MtoA 1.3.1

All versions of MtoA are available on solidangle.com

I have uninstalled my version of arnold and replaced it with the updated files. I have the presets now but Arnold wont work lol. Like rendering or adding materials wont work.

There is an error when I try to add material:

 # Error: CallbackError: file C:\solidangle\mtoadeploy\2017\scripts\mtoa\callbacks.py line 346: Error during callback: nt.Unknown(u'defaultArnoldRenderOptions') has no attribute or method named 'drivers'

Error when I click render view:

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