Black fog at edge of vanilla render distance (MC 1.21.6)
I am getting a black fog at the edge of the vanilla render distance when I enable Iris shaders. I have tried using Photon, Bliss unstable, Bliss BSPT but they all have the same issue.
The issue is goes away while shaders are turned off.
- I have tried disabling vanilla fog via Sodium extras to no effect.
- I have deleted the config files, and created new worlds to no effect.
- The issue also appears on MC 1.21.7
- I am on single player.
- Default resource pack only
Hardware:
- Nvidia 3080 - Ryzen 5 5600 - 32GB memory

Hello there, I will be testing your case now.
Issue is reproducible. Seeing if there's a way to mitigate it.
Very odd, the so-called black fog seem to follow the camera when the renderer is broken.


Issue appears to be NeoForge specific. Fabric does not have this black fog occurring. Forwarding this to @BackSun for input.
Does this issue only occur in MC 1.21.6+ or older versions as well?
Haven't tested that. I can try that right now.
Bug does not present on 1.21.4.

Bug not present on 1.21.5 either.
#Weird visual glitch. reproduce a bug related to the sky in 1.21.5, but without shaders.
