Well, maybe i can create empty model with LUA script, that would load sprite?
BTW, maybe its little offtopic, but how can i use billboards? For example, i want sprite on the wall and so on. I found only coronas, but they are "Coronas are simple entities, like billboards, that are always facing the player."
Is there a simple sprite, or it would be nice to have Faced parameter, wich would select if corona facing the player or not.
