I want to make an invisible block (as it has to be rendered via a TESR). This works fine by returning INVISIBLE in getRenderType and false in isFullCube and isOpaqueCube. But I still have to include a dummy model json, otherwise there will be a silent error on startup (which does not do anything, of course). As it does not really seem to be good practice to have (harmless, but nethertheless present) exceptions, I wonder how to remove the need to create this useless json file (more revelant as I have multiple invisible blocks).
