I was under the assumption that items would automatically get models added for them (like blocks seem to do) unless ModelLoader.setCustomModelResourceLocation is called. Was I wrong about this and all items require ModelLoader.setCustomModelResourceLocation to be called on them in order to work, or have I done something wrong somewhere?

 

It is just that I have a lot of items and blocks which need ItemBlocks, and adding them all will be a pain.

Minecraft will automatically load a model for each

Item

(the one with its registry name), but it won't actually use that model unless you tell it to with

ModelLoader.setCustomModelResourceLocation

/

ModelLoader.setCustomMeshDefinition

.

 

I do this automatically in my mod: Every

Block

or

Item

is added to a

Set

as it's registered (here and here). I then register models for the

Item

s (including

ItemBlock

s) with custom model names and add these to a

Set

(here and here). I then iterate through the

Block

s and

Item

s that haven't had models registered and register the default model for each one (here and here).
