Loop preventing editing attribute values

[Fredrik Averpil]

Hi,

One of our artists noticed that their mouse pointer were quickly changing between pointer and loading indicator when in Maya. This prohibited e.g. changing any attribute values in render globals. I suspected that some process was running and enabled "Echo all history" in the script editor. This made the script editor show that something was looping and causing the issues.

* The loop ended when opening a new scene.
* When re-opening the problematic scene, there was no loop.
* When opening the render globals window in the problematic scene, the looping started.
* By opening the problematic scene, immediately deleting the "vraySettings" node and then open the render globals window, the looping did not appear.
* After some time of working in the problematic scene where "vraySettings" was deleted, the looping re-appeared after some time.

Do you have any idea how we can stop this looping?
It seems limited to particular scenes for us, as we have multiple projects using this V-Ray version and not many of those projects are experiencing the loop.

OS: Windows 10 64-bit
Maya: 2016 Extension 1 Service Pack 5
V-Ray for Maya: 3.40.06 stable build 27040


The portion which was looping:

This is known and it's already fixed. The fix is available in the nightlies from Feb 10 and later and will also be included in the next official release. We already have stable nightlies that you can try.

Excellent, thank you. I'll upgrade to the most recent stable build then.

Cheers!
