this pack is currently incomplete so i have not added all of the weapons yet. in the future i plan to add all of the spoonkind/forkkind, pistolkind, and riflekind weapons as well as some extra textures to use on totems of undying. currently the vanilla trident is replaced by a golden trident and i may in the future add the different 2x3dentkind and forkkind weapons as tridents, although this won't be for a while as i want to have all the shovel weapons complete and added to the pack first

sorry, only just saw this. i am planning to release a 1.20.4 update soonish (might be today, might be a few weeks idk) as ive noticed a lot of issues with the pack since the update that need to be fixed. In general though, if you're having issues with weapons not displaying i would double check you have optifine (or CITResewn if it ever updates), make sure custom items is turned on in your settings (its in video settings/quality), and double check to make sure u are typing the words exactly and that youre using the correct enchantments as some weapons do require the tools to be enchanted for the texture to display.

Just took a look at the files and it seems like there might be a typo with the properties files. I'm sure the uploader will fix it soon, but in the meantime if you want a quick fix I think the following change will fix it:

in assets > minecraft > optifine > cit > [whatever folder]
open the .properties file

change the following line:
  nbt.display.Name=ipattern:ancestral sword*
to:
  nbt.display.Name=ipattern:*ancestral sword*

and that fixed the issue for me.

Are you using Optifine?
