I use this resource pack that adds weapons from Fire Emblem Three Houses as CITs over vanilla tools. One of the features of this pack is to provide an "activated" texture to the Hero relics when they are enchanted. For example, naming a Netherite Axe with Sharpness "Freikugel" will have a custom texture that looks like the orange version of the weapon. I have done this so many times, and the CITs for the activated weapons do not display. Just the normal weapon CIT skin with the vanilla enchanted glint. Is this an issue on CIT Resewn's end, or is it an issue in the resource pack?

type=item
matchItems=netherite_axe
model=optifine/cit/fe3blocks/base/melee
texture=freikugel
nbt.display.Name=ipattern:freikugel

type=item
matchItems=netherite_axe
model=optifine/cit/fe3blocks/base/melee
texture=freikugel_u
enchantmentIDs=sharpness
nbt.display.Name=ipattern:freikugel *

the name patter specified for activated texture is ipattern:freikugel *, with * wildcard it means that the name should start with freikugel and any symbols after. Note that there is a space between freikugel and *. The problem is that the space after freikugel is necessary.
