These assets should not be used inside of the resource pack, these are purely experimental and will crash the game when loaded because 1.12.2 can be stubborn sometimes. 
Thank you for your understanding.

If you are curious to see what these would look like, check the screenshots folder. Otherwise enjoy this pack as it is.

EDIT 8/19/23:

So I actually found out that I was stupid, and that those items were not hardcoded to be unchangeable. I will still keep these files here, however they will not be used as my previous note above suggests. Persistence and the act of revisiting can make things work.
