IPR unreliability

Can anyone tell me why IPR seems to be so unreliable. Sometimes it works as expected, other times it will work for some time then give up, and yet others it will render the initial image and then simply fail to update afterwards. I’m running a very fast 48-core machine with an Nvidia M6000 GPU, so it’s not my hardware. I’m using CPU with default settings.

yeah i get these issues sometimes, unhiding lights doesnt update etc…too random to make a report.

Same here, cannot get to reproduce any of these crashes.. most of them are random
The new debug shading is not usable on GPU.. crashes Maya every 2 or 3 changes so I stopped using it for now.

Do you have any crash logs (.dmp files in your temporary Windows folder, if you are on Windows) that you can send is to support@chaosgroup.com ?

Best regards,
Vlado

I’ll see if I can find the log next time it happens…

Can you tell me what debug shading modes cause a crash?
Do you have a scene?

Isolate selected. It usually crashes on making a change to the scene or when trying to stop the ipr
Here the dump file, I will attach a scene shortly

I’d say this is the number 1 serious bug for workflow in Vray right now. It’s invaluable for lighting and shading work, but constantly stops updating.
