This resource pack makes block models accurately represent the collision box of a block, rather than its hitbox. For example, a fence model and its hitbox is 1 block tall, however it's collision for entities is 1.5 blocks tall. This may throw off players doing parkour with fences, as what would be considered the solid floor is invisible, forcing players to aim slightly higher than what's represented to successfully land on one.
