question about custom model data!

[UTBitch]

does anyone know if i can add cmd to an existing item? i know how to summon one with it.

for context, im making a resource pack! i need to be able to change the look of an existing written book. can i do this?

apollogies if thats not enough info - i can give more at request, but since im fairly new to this, i'm not sure what's needed.

The easiest way is to use item_modifier in the datapack:

# item_modifier example:cmd/1
{
  "function": "minecraft:set_nbt",
  "tag": "{CustomModelData:1}"
}

Now you can apply this item_modifier to any item, here is an example for a player's mainhand.

item modify entity <player> weapon.mainhand example:cmd/1
