This is a weird one and I'm not sure if it's Continuity or another mod like Sodium.

I'm running Prism Launcher and using Fabulously Optimized 5.8.0.

I'm using Faithful 64x as my main resource pack. I created a resource pack of my own that takes the streaks out of the tinted glass texture.

With Continuity set to turn off connected textures, I see my custom texture:

However, when I enable connected textures, it seems to be loading the texture from Faithful for the in-game blocks:

The in-hand model and in-inventory model are both using my custom streakless texture, but the connected textures in-world aren't, they are using the one from Faithful.

Am I doing something wrong with my resource pack, or is this a quirk of Continuity? Thanks!

Ignore this and close it! I forgot the connected glass textures come from a different place than the inventory texture. It's pulling them from Faithful 32x, which I have loaded before x64 to cover anything missing in x64, which apparently includes the tinted glass CTM.

Sorry for wasting your time!
