Rendering issues with Iris, More Culling and potentially other mods

[SplendidAlakey]

MC 1.19.1
Fabric API 0.58.5
Iris 1.2.6
Sodium 0.4.2
Indium 1.0.6
Show Me Your Skin! 1.2.1

To reproduce:

1. Equip any armor
2. Open the SMYS' GUI and set armor visibility to anything that's not 0% or 100%
3. Rendering on the GUI itself is completely broken; rendering in game is ok-ish, but you can see slight issues, e.g. you can see the outlines of the armor while your shadow is in the background (and maybe under some other conditions too, I didn't test it extensively)

Just having Iris installed is enough to reproduce the issue, you don't have to use any actual shaders. Works without Iris, but with Sodium still installed.

I've used this mod with iris myself for a while, and never really encountered issues. The logs mention you run a GTX 980, which should be similar enough to my GTX 1060 that I doubt this is a gpu-specific issue.

MC is generally very quirky with transparency and I'm quite new to rendering, so it's likely I made a mistake somewhere, and I wouldnt know where to even begin debugging that. 😅

Assuming its not my janky code at fault, the only other things I can think of is your graphics drivers being out of date, or some other mod conflicting for some reason. So maybe try updating your drivers or removing other mods until it works.

Does setting your graphics to fabulous make any difference?

[SplendidAlakey]

My drivers aren't the latest, because I generally don't need it, as I never play any new games. But I'll try updating it.

I tested the issue only with Sodium, Indium, Iris, Fabric API and your mod. Logs mention 56 mods because each Fabric API module counts as a mod.

Fabulous setting does not exist with Sodium, which is a hard requirement for Iris. Even if you bring up vanilla menu and change it there, it simply resets back to Fancy.

Ah okay, I really don't know then. I'll try to look into it, but I can't make any promises.

[SplendidAlakey]

Updated my GPU drivers, but sadly that didn't help.

No worries if you can't fix it, the mod is still usable.

Are you able to reproduce this issue on your end? Because if not, that could indicate Iris issues specifically with my hardware.

[enjarai]

Actually looking closely, I can confirm the same issue on my side. I usually never notice it, since I have my opacity set relatively high.

It's still unlikely to be fixed by me any time soon though, due to the reasons stated before. But if you can find someone able and willing to fix it, I'd be more than happy to accept a PR.

Renaming this issue to track similar problems caused by other mods as well.

I'm only kinda late.
With MoreCulling, you can fix the issue by disabling the entity culling option. Which is automatically disabled when you use sodium anyways.
There's a good chance I drop support for it at some point soon-ish...
