InvisibleSkinBlocker

A PocketMine-MP plugin kicking players with invisible/transparent skins.

How it works

It checks for empty pixel percentage in a player's skin texture and kicks them if it is above the configurable value, with a configurable message. Also supports changing the skin in-game.

A little warning

Keep in mind, skin textures normally already contain empty pixels. This plugin does not bother with calculating which pixels of the skin are actually rendered, but runs the percentage checks on the entire texture file. For this reason you most likely do not want to change the percentage value too low, I found 75 to work pretty well.
