Title: bloom and glare corona 12 in animation
Post by: Serj Scennikov on 2024-07-14, 08:28:21
Strange behavior of bloom&glare in animation.
Some of the frames rendered without it. Have to render those frames again.

As seen on the screenshot attached some of the frames are empty without any bloom.

This is happening random in every shot rendered both locally and network rendering.

Was the light source or its intensity in those frame too small or less for the bloom to be applied?

I also have this problem. The sky halo generated by HDRI is very random, with some frames having halo and others not. The previous version of Corona did not have this issue

There's no bloom at all.
See attached files, where frames 74 and 76 have bloom applied, and frame 75 are completely empty.
This occurs randomly in each shot and each project. Random frames are completely black without any bloom applied. This can be seen by the size of the files.
If i re-render frames with missing bloom the same problem occurs once again on random frames. In the current state bloom and glare are completely useless in animations.

Can you start a ticket and send over your scene to investigate the issue?

Sorry for late response.
Sent you a bug report.
Request #274794

This problem occurs on network rendering using backburner. Cannot confirm if there are same problem when rendering locally.

This problem only comes with the new VFB. Try switch back to the old one (should be done on all your render nodes), and it solves the flickering.

Also some additional info we've noticed:
- Bloom and Glare computed on the slaves, but not burned in to the elements
- Sometimes the Beauty element has the B&G burned, and the Lightmix element do not, and vica versa, same with the B&G element
- For us it seems the problem occured during saving the separate elements
