Many generators allow users to create multiple name-based variants for a single item quickly, which is perfect for "furniture" packs that use renamed items to represent things like chairs or tables.

While they generate the file , you still have to manually place it in the correct deep-subfolder directory of your resource pack.

Manual CIT creation requires setting up a strict folder structure ( assets/minecraft/optifine/cit/ ) and writing code like type=item , items=gold_nugget , and nbt.display.name=regex:Gold Coin .
