cold terrace
Last time I made a mod for carpets https://discord.com/channels/507304429255393322/1247875928537694209
I managed to release it, port it to different versions and make an additional library, thanks to which I now make a similar mod but for glass panes
So, yes, you can place glass pane vertically

You can see similar logic in Vine blocks
Or read about this in thread from first post
pls port this to 1.20.1
I ported the previous mod to versions: 1.16.5, 1.18.2, 1.19.2, 1.20.1, 1.20.4, 1.20.6, 1.21, 1.21.1, 1.21.3
I plan to port this mod to the same versions

Do you end up with z-fighting on the corners when two sides overlap

So that means you can only have the same color of glass pane in the same block space then? Or did you make it so each side states which color it has (which might be better as a BE for loading time)?

its like glow lichen. you also cant have different types in one block
codewise that would be a nightmare

I don't think it's much of a nightmare, it's just using enum BlockState properties instead of boolean ones (and a bigger blockstate .json file), here's an example (as a Github Gist) I just made (most of it would be the same/similar for single colored multi-pane blocks anyway, like for the collision shape), and here's how it looks in-game.
I only added 3 colors, but it's not too hard to add the remaining ones, though it could slow down resource (re)loading a bit and not be compatible with modded panes with that method, but if it was done with a BlockEntity these would not be issues (well, it could still be hardcoded to vanilla panes).
Also anyone is free to use that code if they want.

Load into a debug world and see the joy you have created with that :p
18 possible values (clear, none, and the 16 colors) with 6 different faces would be over 30 million block states

True (though even in vanilla my PC struggles with debug worlds), hence why I've said twice making it a BlockEntity would be better in that aspect (as well as making it compatible with modded panes)
Plus I only made the 4 states (none, clear, white and orange) you see in the picture so technically I didn't create that "joy" yet 😉
