Shift-Dragging lights crashes IPR

[Pixelcon]

This happens quite regularly for me and maybe as often as every 5th light created will crash max. Sometimes I get a backup-saved type of crash, sometimes it's just a hard crash to desktop.
I can't give you my current scene as it's massive but I don't feel like this is a scene-specific thing anyway. Just wanted to bring it up...

Max 2021.3 and Vray 5 update 1.3


edit: actually creating a light as normal crashes max during IPR also.

Hey Pixelcon,

Cannot seem to make it crash on a simple scene, see the attached recording.

A scene would be best, I'm afraid. If you could strip it down a bit and forward it through our contact form, it would be great. It might be a combination of things causing this, so we need to troubleshoot. Make sure to mention this thread in the email, thanks!

I'll see what I can do but I have a feeling as I strip the scene down, the crashing will stop. Stability on a simple scene is great, but I never work on simple scenes

True, you can send the full version as well in case you can't reproduce the crash on a stripped one. We'll have a look and see what might be causing this. Much appreciated!

Well I'm having a lot of trouble isolating it. As far as I can tell it's not a specific object that is causing it, but as I unhide layers the scene becomes unstable and crashes when copying lights. If I start IPR and shift-move the light (select $VRayLight002) in the top viewport I almost always get a crash.
Scene is uploading now.
