[Max] I need help! / Bloom Glare results inconsistent with Light Materials in Animation

« on: 2021-10-19, 16:39:01 »

Been having issues with certain cameras in the same scene not adding light material objects to the bloom & glare pass.  This error is inconsistent and even replicates on the same machine/nodes.

Currently setup with a UHD cache per camera, could this be an issue with my render settings?

Thanks for your responses.

Maru, unfortunately I found neither of those solutions to have worked. 
1) Even with the longer frame render times the difference in the fireflies was just as exaggerated.
2) Fractionally reduced glossiness has already been applied to the scene, for this process to work I found it needs to be considerably lower than 0.9 to reduce the fireflies but that also damages the overall quality of the materialisation. 

aref3dsmax, on the other hand ive found your solution to work pretty well!  With some experimentation of different clamping values and alterations to the post processing I've been able to achieve the desired result without effecting the over all scene.   I feel I initially overlooked the highlight clamping settings and assumed they were for compression. 

Thank you both again for your input and would recommend the Highlight clamping solution to any one else having this issue.

With car materials or any kind of high IOR metallic material there seems to be a constant discrepancy around the calculation of the fireflies between animation frames, which results in 'dancing fireflies' as seen in the attached video file.

I've seem similar issues posted on the forums before but I am yet find a real solution for this issue & have so far tried many workarounds with varying success:

• Using UHD Cache (both clean and from file)
• Increasing UHD Cache precision
• Playing with GI vs AA Balance
• Different Denoising Techniques
• Dramatically reducing all reflections on materials in the scene (very unpreferable as reduces scene quality)
• Turning off light visibility in both reflections & refractions (again very unpreferable as reduces scene quality)

It has now happened across multiple files with different assets & lighting setups, also across bother Corona 6 & 7.

Any help or suggestions would be much appreciated.
