Lens effects don't work / produces black image in VFB

[Pixelab]

I'm loading a series of vrimg with float values above 1.0 (up to 10.0 and above), rendered from the same scene and some images just refuse to renders Lens Effects when opened in VFB (it 'renders' based on the progress bar but the elements stays black when done)

It's weird because other renders from the same scene renders effects just fine.

Renders are cubemaps 24576x2048 and are around 5Go each

I can't share the files since it's highly confidential.

Is this a known issue ?

Try applying the Lens Effects via the vdenosise.exe tool (see how here). If that doesn't help, could you try reproducing the issue on a simple scene and attach it here?

Thanks, it worked even if the technique is a bit tedious for still images

I can't reproduce the problem on a simple scene (it seems to affect large images, 5Go+ 24576x2048 in this case)

I'll wait till the confidentiality is lifted on this project and send you the image to investigate if that's ok ?

That's fine. You could crop out the light source part as well.
