Addakis

Thats how I had it initially but it still gave me the model not found model/texture.

Yeah i get that. But doesnt mcp not work any more? I dont know of any other way to get to the class files. Other tha. Searching through the mess that is not decompiled 1.12.2 files

I figured it would be... I based it off of minecraft's cobblestone wall json. Also the link shows directional not based on neighboring blocks.

That's what I meant, sorry I'm new to modding. My current blockstate is as follows. { "multipart": [ {"apply": {"model": "ai:copper_cable"}}, { "if": { "Up": "true" }, "apply": { "model": "ai:copper_cable_turn" } }, { "if": { "North": "true" }, "apply": { "model": "ai:copper_cable0"} }, { "if": { "East": "true" }, "apply": { "model": "ai:copper_cable_turn", "y": 90} }, { "if": { "South": "true" }, "apply": { "model": "ai:copper_cable_turn", "y": 180} }, { "if": { "West": "true" }, "apply": { "model": "ai:copper_cable_turn", "y": 270} }, { "if": { "Down": "true" }, "apply": { "model": "ai:copper_cable_turn", "y": 270} } ] } Note: I have tried both "if" and "when" What am I doing wrong?

Im looking to adjust my block models based on neighboring blocks but Im not sure how to implement and up(), down(), east(), etc methods which can be used in my blockstate json. Any help is much appreciated. Thanks!
