[SOLVED] Registry Question in Modder Support Posted January 31 Just now, diesieben07 said: That is not possible. Either you register items and blocks always, or you don't. Again: What do you mean by "appear"? alright. I meant as being registered and you can see its presence... lol i don't know how else to explain. So I'm just gonna register it and hide it from the creative tab if the mod is not downloaded and vice versa if it is.
