I am new to the forge API and could only find information about DefferredRegister for blocks and items. So I attempted to use IRenderFactory, but found out that in 1.16- they dont use classes anymore, but EntityTypes. I attempted to use my entity type that I had for the custom entity, but it took in a EntityType<?> so when I used it. It gave an error. If anyone has had this error before and found a solution please tell me what you did.
