Help with content mod. Not displaying textures, simple name or crafting recipe

[An Inconspicuous Table]

G'day,
trying to make a content mod for hanging vessels but I'm out of my depth getting it to render textures in game, display names correctly or have functional recipes.

They are in the creative menu, can be placed/broken, have the vessel lid animation and the correct shape [just missing texture].

I'd be happy with it only working for one colour of vessel (black or brown as they are the pit kiln ones)

Any help would be appreciated (or if you want you can use the shape I made for your own mod)

Textures:
- Your shape file doesn't contain legitimate texture references. They only contain names not paths.
- Your blocktypes file doesn't contain any texture references. This is very important if you want to support more colours (like different clay colours).
In both cases compare your files against the Vanilla storagevessel files.
Because you are essentially creating variations of Vanilla assets it is perfectly fine to utilise the Vanilla textures. See Referencing Domains for a brief HowTo.

Recipes:
- All files contain errors and are, as a consequence, not read by the game.
Enable developer mode in the settings (interface -> developer mode. dev -> error reporter). This will give you error messages in the loading screen. It's also good practice to always have an eye on the logs (particularly client-main and server-main).

(Don't mind me, just copy-pasting my answer here in case anyone stumbles across this question in the future having the same issue.)
