[SOLVED] [1.12] Prevent Forge looking for block models with vanilla TESR? in Modder Support Posted July 5, 2017 6 minutes ago, Choonster said: Minecraft calls BlockModelShapes#registerBuiltInBlocks for the shulker box Blocks, which means that BlockStateMapper#getBlockstateLocations and BlockStateMapper#getVariants return an empty Set/Map respectively when called with one of the Blocks. You can achieve the same result by implementing IStateMapper#putStateModelLocations to return an empty Map (using Collections.emptyMap) and registering an instance in ModelRegistryEvent using ModelLoader.setCustomStateMapper. Thank you! This fixed it! However, I now noticed something that may have been a problem before, but I didn't realize until now. The block-breaking particles from the trapped shulker boxes are the purple-and-black "no texture" image. Without a block model, how do I define the particle texture?
