Version Info

• Minecraft, 1.21.7
• Fusion, 1.2.7

What mod loader are you using?: Fabric/Quilt

Are you using OptiFine: No

Description of the Bug
Connected glass for all glass types is not working correctly. A thin border between the blocks can be seen for all edges of the block, even through to the other side (see screenshot below. It's a little difficult to describe in text). This occurs on both Fabric and Quilt, with Fusion as the only mod installed, and on both single/multiplayer. Switching from the default connected textures pack that comes with fusion to another fusion compatible one did not fix the issue either. I have also restarted my game and my computer.

Steps to Reproduce
I didn't do anything to make this glitch happen. I logged onto Minecraft 1.21.7 with all my Quilt mods and this was already the case. While the glitch occurs even without other mods, the mods I was using when I first launched the game were:

• Fabric API
• Sodium
• Lithium
• Entity Culling
• Dynamic FPS
• EMF
• ETF
• Fusion
• Iris
• WI Zoom
• LambDynamicLights
• MaLiLib
• Litematica
• MiniHUD
• WorldEdit
• Shulker Box Tooltip
• CraftPresence
• UniLib
• Command Keys
• Mod Menu

Sorry I can't provide more info on how to reproduce. I hope that the information provided if helpful and if you have any questions I will answer.

Screenshots

I mistook the "Fused Glass" texture pack I was using as the default option (I started using fusion a while ago so I forgot I downloaded it separately). The other pack I tried is Midnighttiger's default connected textures. It seems that neither of these texture packs are made for the newest version of Fusion (Midnighttiger's is for 1.2.2 and Fused Glass hasn't been updated in over a year). Do you know any packs for Fusion that are up to date or how I can "fix" one of these packs to work on the latest version?

Switching from the default connected textures pack that comes with fusion to another fusion compatible one did not fix the issue either.

Fusion does not have a 'default connected textures pack'. Fusion itself does not change anything. It depends on the resource pack you are using.

From 1.21.5 to 1.21.6, Fabric changed its API to where you now have to set the cull direction separately from copying the baked quad data which I did not realize, hence just none of the quads would be culled.
It should be fixed now in version 1.2.7a for Fabric 1.21.6 and 1.21.7.
Thank you for reporting the issue!
