‘‘Transparency’’ would be a setting available in texture customization, and it would go from 0% to 100%. Transparency would determine how much the player can see through the block/model, and the amount of light that can go past it, allowing players to create a kind of ‘‘glass effect’’.
It has been already tested like some sort of experimental feature some time ago, especially in the first versions of Blokoto, but it was only shown as something translucent in the preview, because the block actually didn’t got invisible in-game LOL. I remember Ink telling that it’s something difficult to achieve this behavior in such a pleasing way because of its rendering, but i guess it may be available soon, but probably will take some time to reach what is supposed to be.
