in minecraft, blocks are only visible if one of their faces are visible, i.e. blocks are not rendered unless it is required that they are rendered. I want to make a game which has a similar dig mechanics to the game "Treasure Hunt Simulator" on roblox, but my only idea on how to do this sort of optimization would be to clone the block that was mined, and set the position of the exposed block(s) to where they should be, but how would i go about checking if there is a block on the SIDES of the mined block already?
I hope my phrasing was not too confusing
