I've rewritten the glowing post shader to remove the black outline and stop it from covering the entity, it looks better imo. Also, it's faster than vanilla so you'll lose less fps while there's glowing entity in view.
Feel free to use it anywhere!
Mc Version
It works on Minecraft 1.9 and all the way up. But if you're on below Minecraft 1.14, you'll need a game restart after applying this pack.
(Technically it works on all version because there's no glowing effect before 1.9)
Installing
It should be installed like resource pack.
Why is it in Shaders category? Because this pack only modifies post shader and there's Vanilla filter in Shaders category. So I thought it's technically a resource pack but logically a shader pack.
