Textures broken by shaders mod

Armors textures look broken when using custom shaders mods (1.17+)

This bug was fixed in ItemsAdder 3.0.3

If you see broken textures make sure you are using ItemsAdder 3.0.3 or a more recent version. Also make sure you regenerated your resourcepack using /iazip (and read the hosting tutorial if needed).

With shaders (bug)

Without shaders (no bug)

ItemsAdder 3.0.3 update

What was the cause of this bug?

Optifine issue

Optifine has a limitation which doesn't allow custom armors to work correctly if you have any custom Optifine shader installed.

You have to disable the Optifine shaders temporarily or temporarily live with the issue.

I already contacted Optifine developer about this: https://github.com/sp614x/optifine/issues/6391

Iris Shaders issue

Iris has a limitation which doesn't allow custom armors to work correctly if you have any custom Iris custom shader installed.

I already contacted Iris developers about this: https://github.com/IrisShaders/Iris/issues/1042
