Camera motion blur in IPR still an issue?

About three years ago I reported a bug with moving cameras not displaying motion blur in IPR. It is still an issue in the current release.

Can this be fixed at all?

There surely is a reason for it. I’ll ask the devs about it and write back.

EDIT: We’ve simply not started working on it yet. Note that the issue is logged (internal bug-tracker id: VMAX-6240) and the devs are aware of it.

Fixed in V-Ray 6.1.

Did not have the chance to test yet, but this would be great news!

Was this eventually resolved or is it still an issue? Also having trouble seeing motion blur in GPU IPR. Latest version here. thanks!
