Resource
data class ResourcePackData(val texturePath: String? = null, val textureBytes: ByteArray? = null, val modelPath: String? = null, val modelJson: String? = null)
Resource-pack data for the item. Provide a model via modelPath (path to a model JSON inside the jar) or modelJson (the model JSON content itself); if both are null a default item/generated model is built from the texture. The texture comes from texturePath (a file inside the jar) or textureBytes (raw PNG bytes, e.g. generated at runtime); both are optional — omit them when the supplied model brings its own textures. modelJson takes precedence over modelPath, and textureBytes over texturePath.
