You must download the DataPack here: (DataPack Download Here)
This resource pack is the one you must use to correctly see the blood in the Blood N' Particles datapack.
That datapack consists of adding a touch of immersion to the game, adding blood and particles every time you receive damage.

The more damage you take, the bigger the pool of blood will be.

The blood will disappear after a while, so don't worry about the lag ;)
After a few seconds, the blood on the floor will disappear with a smooth shrinking animation

If you have any suggestions for the ResourcePack or want to report a bug, don't forget to leave it in the comments :D
