Issue rendering Motion Blur

[haniel1107]

Hello,

I have an issue rendering motion blur with a mixamo rigged animation.
When rendering in animation mode, mb appears only on the first frame.

If I render any frame as still, mb is ok?
Any idea what's wrong?

Thanks

Did another test, same result... when rendering animation, MB is not working.. 1st frame ok, following frames no MB...

Please, tell me I am doing something wrong... using latest nightbuild

Hi haniel1107, I can not reproduce this issue. Neither with the last official release (hotfix 1), nor with the latest stable nightly build.
Can you share a simple scene that reproduces the issue? Also, would you describe exactly what render setup are you using (with/without DR, with VFB or Picture Viewer, command line)?

Hi Deyan, the scene with the runner is above (First Post in a zip).
R23 with the latest night build on Windows. Threadripper 3990X / 128 GB Ram / RTX 2080Ti

Rendersettings all by default, with VFB, no DR.. Anything else you would need?

Thanks..

Hi Deyan, made a 2:22 Video.. as said before everything by default except render time for this video...

Here is the simple scene with the wheel

Same happens on ChaosCloud

We reproduced the issue with both your scenes. I'll investigate this today.

Thank you!!

Hi Deyan,
could you figure something out?
If I add a simple cross in the back, the cross got MB on the following frames...

Hi haniel1107, I managed to pinpoint the problem yesterday and will finish fixing it today - the fix will be available in the stable builds in a day or two.

[haniel1107]

Super, thank you very much!

[haniel1107]

Hi Deyan, do you know if the fix is really coming today? Just need to know it, otherwise I have to go back... to 3-7

Hi haniel1107, sorry for the delay. During the testing of the fix we unveiled a deeper problem that will require further effort. I'll keep you updated, but probably the fix will not make it to the stable nighty builds tonight or tomorrow.

Ok thanks for the answer... then I think it is safer to switch back.. as for the deadline....
