I'm currently in the process of designing a mod. I've got all the necessary architecture in place for the mod items and blocks to operate properly; the ore can be placed as a 3d render and ingots drop onto the ground. I have two textures as of now (Cobalt Ingot and Cobalt Ore.) I also have a .json file to 'attach' the Cobalt Ingot texture to the cobaltingot item (defined in 'Item game + name registry.) None of this works. I've followed tutorials etc, checked what I've done, but I'm getting nothing. How can I sort this out? On top of this, my .lang files don't work. I don't know how I can sort this. Any ideas?
