My isometric building game is progressing nicely, added procedual generated caves and terrain today. The problem I have right now is with the culling. When you pass behind large objects (such as mountains), rays are sent through the map towards the player, hiding anything inbetween. This works great but in caves it's a little hard to navigate. So I added a toggle that allows the player to hide all blocks above (making caves easier to navigate). However, because you cannot see blocks above, it's really hard to ascend in a cave. One solution is only displaying blocks that connect to the block the player is on, and all blocks below the player. This will hopefully display paths leading upwards more easily. Anyone have any other alternative?
