hello !
i don't know if it's due to mojang's changes to rendering in this version but stars won't appear (at night or daytime) in the sky with shaders (i remember in previous versions it was a mix of both vanilla(sga) and shader stars)

here's some logs

different shaders act differently, amd theres not really anything i can do about anything

sorry ! what i meant was something changed between 1.20.1 and 1.21.6 that made them incompatible, i just tested both versions with same mods and shaders and wondered what could have happened

After a few tests i can confirm that the change occured from 1.21.4→1.21.5

btw, not really the place but i gotta thank you for how amazing your client execution mod is, it finally allowed to combine mods with datapacks, you're awesome :)

1.21.5 changed a bunch of how rendering works. there is nothing i can do about this

and yeah i got enough people asking for server compatibility for my various mods that i decided to just make a single thing to fix all my problems lol

thanks ! i'm gonna continue this thread in iris/complementary shader's github to find if there's any answers over there :)
