Im making a resource pack and the double chests are broken (they are black and purple) I dont know what caused this or how to fix it, I also found out that the chest textures were odd (the bottom of the lid was on the top and the hole in the actual chest bit was on the bottom) but i fixed them, please help
For questions like this one it's always helpful to state what you have changed and what could lead to your problem. Black and purple usually means something is wrong with the block model. If your chest has turned into a full block with black and purple pattern, something is wrong with the model file. If your chest still looks like a chest and only the textures are missing, there's an error in your texture references (also in the model file).
