So I recently followed a tutorial on how to setup connected textures for Iris, because that was the one feature from Optifine I greatly missed. Upon opening up the game, all the mods I was told to installed were properly there (namely: Continuity, Iridium, Iris, Mods Menu, and Sodium). However, once entering a world the textures were not connecting. I checked the options in the mod menu for Continuity and all of them were properly set to connect the game's textures.

I have attached a list of the mods my latest log includes, if any other information is needed that I am leaving out just let me know.

Did you enable the default resource packs?

Ah there we go, did not see those before. The issue has been solved, thank you!
