IPR Render shuts Slate Down

[RobH22]

This issue is similar to this thread: https://forums.chaosgroup.com/forum/...when-ipr-is-on
but slightly different so I started a new one.

I used to be able to tweak a material with the IPR window running. I could watch color or parameter changes. Now, if Slate is open, as soon as I click IPR, the Slate window is closed. When I click IPR 'Stop' the Slate window reopens. I was hoping that the new version 3.2 would address this issue but sadly it did not.

Are you on Max 2021?
I'm interested in this too as I reported the same issue 2 days ago, and the support team couldn't re-produce it .
I will test with new released build and see if that will solve it.

Thanks for the report. We are aware of the issue (internal bug-tracker id: VMAX-9737). It occurs in 3ds Max 2021. I'll bump its priority additionally.

Yes, I'm on Max 2021 but it also occurs with Max 2020. It looks like Chaos is aware of it. Hopefully a fix won't take too much time.

Update. I installed the latest Substance plugin for Max 2021 and the problem stopped mostly. I can now use Slate and watch it update in an IPR render. That's working fine. Only other issue I'm seeing is that 'Region' render won't function at all. No matter what, the entire view is rendered.
