After overriding SerializeState and UnserializeState and setting PLUG_DOES_STATE_CHUNKS to 1, how do you get those functions to actually be called during saving and loading the file in the VST host, respectively? I got this to work years ago for a different project but can’t get it working now. IPlugChunks also only calls these functions during preset saving and loading while using the plugin, not when it is reloaded or closed.
