Inverted Mob Filter

The Inverted Mob Filter is a block added by Dark Utilities. Inverted Mob Filters block a certain type of mob from passing but permit all others. There are eleven different kinds, each with a slightly different crafting recipe. The block texture indicates the type of Mob that is blocked through.

Testing indicates that mobs see Inverted Mob Filters (Player) as being solid blocks. When they attempt to walk on the filters, they fall through.
