I'm trying to make a resource pack to make glass textures connected using this mod. However, the issue I'm running into is that there is no way to change texture based on connectivity in the Z-axis. This means that the top of the glass panes always have a texture on them even if they are connected to another glass pane on top. For non-transparent blocks, this is no issue. However, for transparent blocks like glass panes, Z-axis connectivity is important.

Would be great to have a texture type that implements Z-axis connectivity. It would only need 1 extra texture in the group, which represents what to show when the face is covered by a "connecting" block. It could either be its own texture type (maybe "depth" in addition to "vertical" or "horizontal") or maybe as an addition to "full" which has room for an extra texture in there anyways.

This could be expanded where you can specify which face of a block you want to detect from and you can offset that by 1 block to do a certain feature if you wish. Hence would also cover the feature request I opened too #52
