Instead of using the standard 16x, it uses 64x textures. The first thing that the MineLoL resource pack does to improve visuals is to upscale the resolution of textures. MineLoL is a resource pack that is meant to bring considerable improvements to Minecraft and as the developers state, make the players smile. It is anything but a joke or a MOBA-inspired resource pack.
It is also anything but ridiculous despite its uses of LoL in the name, an acronym of laugh-out-loud. You might be tempted to think that the MineLoL resource pack is related to League of Legends but it is not.
