Hi guys!
We switched our project from UE 5.5 to 5.7, and now all collisions and all unlit materials are making those glitter effect (screen below, christmas time !).
MORE DETAILS:
- My coworker does not experience this issue on his side (he is on Nvidia while I’m AMD, GPU → Radeon RX 6650 XT).
- My drivers are updated.
- Changing anti-aliasing method didn’t fix anything.
- Changing the bloom treshold or method on my Post-process volume didn’t fix anything.
- If I turn Megalights off, I don’t have this issue anymore (but it’s not a solution…).
- Didn’t have this issue with 5.5
WHAT WORKS (more or less) ?
- I can “fix” temporary this issue with 3 methods, but they’re not optimal:
1/ Making every unlit material some lit materials (but it doesn’t change the collision glitter effect, though).
2/ In my post-process volume, changing the bloom to 0 (was 0.6 before) helped on several material issues (not all, though). Thing is… I like my bloom :’(
3/ In my post-process volume, changing “Highlight Contrast” (in Local exposure) to -1 (from 1) fixed the glitter effect… but it’s ugly on my scene, so turned it on again.
None of these fix are really helpful.
Any idea, guys? Anyone experienced the same thing?
