Arnold for Maya refuses to install in some computers

[Anonymous]

Hello:

I have installed Maya (Version 2019.2) in 5 computers, at work and home. Some are running Windows 10, some Windows 7.

In two of them, I have repeatedly removed and reinstalled Maya. I select Arnold (and Substance) to be installed. However in those machines, Arnold is never installed. I am getting the following messages every time I start the application:

// untitled //

The "mayaSoftware" renderer will be used instead. To prevent this message from being displayed in the future, set the environment variable: MAYA_NO_WARNING_FOR_MISSING_DEFAULT_RENDERER=1 //

Please help.

TIA

: The renderer "arnold" used by this scene, is not currently available

That usually means only that the MtoA plugin is not loaded.

What happens if you open the Plug-in Manager? Is MtoA listed? What happens if you load it?

Fixed. I went into:

Windows | Settings/Preferences | Plug-in Manager

It seems that for some reason, in some computers the "Auto load" option is not selected by default.

Thanks!
