bloom and glare bug?

[britbunkley]

I bought a model made in Max 2022. (I'm using version 2023 with the latest Corona build.)  I have been doing a simple animation with the camera moving slightly from left to right with a springbok in the room in 450 frames. The glare on the ceiling lamps changes on some frames to a dull orange. So for instance on frame 255 the glare on the lamps is bright, but on frame 256 the glare is dull and slightly orange. In fact, on some frames, I saw the glare change to a dull orange as it was rendering

I did a few tests using the region rendering on the lamp section (to overlay in Premiere). On one frame, when I turned the bloom and glare on and off a number of times the glare mysteriously went right and was no longer the dull orangy colour. Any ideas on how to fix this bug?

Hi,

Unfortunately, this can happen sometimes. Bloom and glare can vary for the same frame with region rendering too.
One way of getting rid inconsistent bloom and glare, for now, is to use the legacy mode. As I see your bloom and glare effect is not complex and it should be fairly simple to get the same result using the legacy mode.

Of course, we have this reported and will keep you posted in case of updates.

How do I use the "legacy mode"? I just turned off the bloom and glare for this one and re-rendered the lights a region to mask out in Premiere, and it was OK.

You can find it in Render Settings > Camera tab > Bloom and glare menu.
