Render Element "Enable" Override = Can't Switch Between Render Layers

V-Ray V-Ray for Maya Issues
1

There appears to be a bug where if I create an override on the “Enable” attribute of a render layer (in order to disable it), I am stuck on that render layer and can no longer switch between render layers. If I delete the AOV’s palette that is automatically created from the override, the problem vanishes and I can again switch between render layers.

Using Maya 2018.3 + V-Ray 3.60.01

Also, this message is generated in the script editor when attempting to switch away from the render layer with the AOV override:

Hi,
could you please try with the latest official 3.60.04 or 3.60.05 since this was caused by changes introduced with the update to Maya 2018.2. We fixed the issue but the fix is not in the current V-Ray 3.60.01 version that you use. Let me know if you still have this issues after the update.

Thanks, Ivan. Could you please provide a direct link to download those versions? Our systems engineer could not find a *.04 or *.05 version where he normally downloads the software.

V-Ray 3.60.04 is the current official version and should be available in the Downloads section at www.chaosgroup.com after you login with your username and password. V-Ray 3.60.05 is a stable nightly version available in the Nightlie builds site. If you don’t have access to the nightlies site please write a mail to support@chaosgroup.com with a link to this thread and ask for access to the V-Ray 3.60 stable builds. Let me know if you need more information.

Just to follow up on this… the 3.60.04 upgrade solved the problem. Thank you!
