CTM has non-connected textures on glass. 1.15.2 OF Preview G1_Pre2

Like it says in the title. Heres a gif of the issue.
I've been told it's an OptiFabric issue and not an Optifine one. Hopefully it's not hard to fix.

I've had this happening to me with glass panes since at least 1.14.4. I've not noticed anything like this with regular glass.

I have no idea why this happens

It looks like the textures on the "back" side of glass panes (north side when the panes are oriented east-west, east side when they're oriented north-south) are mirrored from their normal texture, which is most noticeable on the end pieces. This only occurs when using OptiFine via OptiFabric.

This does not occur when using only OptiFine.

It only seems to affect the glass panes, not the other blocks that use connected textures like glass blocks, sandstone, and bookshelves.

For clarity, in the first set of screenshots, I'm running the following:

• Minecraft 1.15.2
• Fabric loader 0.7.8 build 184
• OptiFabric 1.0.0 beta 4
• Optifine 1.15.2 G1 pre3

After playing around a bit, I've found that this bug was caused by a change in fabric api between builds 197 and 198. This means it would have first been noticed in OptiFabric 0.4.3, the first version to support Minecraft 1.14.4, since its minimum fabric api version was bumped from 0.3.0 build 191 to 0.3.0 build 200. I'll see if I can't track down the associated commit in https://github.com/FabricMC/fabric/

In both sets of screenshots, I'm running Minecraft 1.14.3 with Fabric loader 0.4.8 build 155, OptiFine 1.14.3 F2, and Optifabric 0.4.2.

Fabric API 0.3.0 build 197

Fabric API 0.3.0 build 198

I think I have an idea why this isnt working correctally. I dont think Fabric API is adding optifine as a resource pack.

[ilepow34]

Based on the timestamps on GitHub and CurseForge I think this is the commit that caused it: FabricMC/fabric@7495ea2

Should I open an issue there too?

[modmuss50]

I think I need to add optifine as a resource pack ontop of being a mod.

I didn’t understand anything, but when it will fixed?
Sorry for the dumb question.

[modmuss50]

I think ive made some progress fixing this.

It did require adding optifine as a fake resource pack, I dont think this will cause any issues:

This fix will be included in the next beta version.
