And once you have read it and possibly have questions come back and ask and I will answer.

This is a link to my ModelRegistryEvent for a WIP mod if you trace it back you will see how it all comes together. I feel it might be easier than explaining it all to you with a back and forth.

Who told you to do anything with those methods?

First off this is a horrible modid Secondly is the folder path assets/bf/recipes? Edit: also is there any error in the log?

Does observedNeighborChange get called?

You're passing a null item into setCustomModelResourceLocation.

Patient: Ouch doctor it hurts Doctor: Where does it hurt. Patient: Right there Doctor: Where is there?

Where are you calling ModelLoader.setCustom...

Could it possibly be the fact that the method swapBlock is called twice

This isn't true forge will automatically append your mods modid as long as it is your mod that it is constructing, aka dont use static initializers.

In your case 0, but some items have a magical number that allows you to differentiate between different states, or in some cases a "new item". Also dont disregard the advice of the other people especially DaemonUmbra. They know what they are talking about a lot of the time.

If you use ModelLoader.setCustomModelResourceLocation(item, meta, new ModelResourceLocation(getRegistryName(),...) then it will look for a file at assets/modid/models/item/registryname.json

Do you have the import?

Define breaking. Post updated code, preferably the whole class.

Simply put you need an item instance so new Item(...). Then you need to subscribe to the RegistryEvent.Register<Item> and register your item. Then subscribe to ModelRegistryEvent and call ModelLoader.setCustomModelResourceLocation(yourItemInstance, the metadata, and then the model location). The model location is a ModelResourceLocation. Typically it is instantiated by passing in your items registry name and then a string called inventory.

You are also not declaring your variants correctly in the blockstate json. Take a look at what Draco said earlier.

No use the name of this blockstate file.

Instead of backsplash_base and backsplash_bricks put the name of your blockstate file.

Then why are you referencing other blockstate jsons?

This is not a forum to help out with non-forge projects seeing as how this is The Minecraft Forge Modding Support Fourm.

Then dont just say you're new to programming in general, it isn't clear what you mean. For items override Item#addInformation(). For blocks override Block#addInformation().

Check this out.

Save its uuid

You're still not saving a reference to the entity, your creating a new entity every time.
