Arnold 7 menu not showing up in maya 2022

[Anonymous]

The top menu for Arnold does not show up for me using Arnold 7 in Maya 2022.2. It's loaded in the plugin settings and I can adjust settings but I can't access the drop-down menu. I can't add Arnold lights etc. I installed using the installer not manually. Any ideas on how to fix this or is this a bug?

Never seen that before in 10 years.

Is there anything logged in the script history?

What OS is this?

Ok I turned off loaded in plugin manager and turned it back on, it appears. I reloaded Maya but it doesn't load again. So it's a bug of some sort, simple fix but it works, just have to reload each time.

I'm on windows 10, fully updated. Here is a copy from the output window but I don't exactly understand the issue. Thanks for chiming in.

All those messages are for an older version of the NVidia mdl plugin. They shouldn't cause any problems with the rest of the MtoA plugin (like the Arnold menu).

mdl_arnold is part of the Nvidia MDL SDK.

If the Arnold menu is not there, try running this Python in the Maya script editor:

from mtoa.ui.arnoldmenu import createArnoldMenu
createArnoldMenu()
