Glass Panes rendering middle seam

[Endoman123]

Hi, as the title says, glass panes are rendering the middle seam even when connected.

I am using OptiFine with Connected Textures disabled.

Does this occur without OptiFine?

It does. With more testing, it seems to be a problem with the glass model definition.
I have not been able to fix it, and using the model JSON from the ConnectedTexturesPack doesn't fix it. Instead there's an issue very similar to Chisel-Team/ConnectedTexturesMod#107.

Yeah this is related to block occlusion code. It should be occluding vertically for matching panes. Vanilla skips this occlusion here iirc. I'm not sure the best way for CTP/CTM to work around this.

We have a working model in Chisel that should be ported over to this.
