[1.15.2] How to make connected textures?

[starstorms21]

So i want to make a fancier glass block, where it has connected textures to apear clear. I have a all the variants of the texture i could ever need but im not sure how to go about actualy making the blockstate/model/whatever is needed to actually allow the textures to connect. Any help/tutorials/links would be great!

Well you have a block with six faces. Each face will connect to a different block on four sides. However, it will cover all six faces regardless. So, you will need a state per face (SixWayBlock has an example of this) to check what textures should be present. From there, the texture can be updated based on the corresponding states of the surrounding blocks. You should probably use a data generator for this.
