I’ve seen alot of renders with backgrounds and changed colors to like the sky and so. How do I do this? Do i have to make a large cube and put my objects inside it to make a room or are there some settings where i can change this, because i want a space background with stars and such (probably small icospheres that emits alot of light) but still, i dont know how to make the background black and neither i know how i could make smoke and i need to know how to duplicate objects. Can anyone help me with this?
EDIT: Never mind, found out how to change background color >.< but i still dont know how i would make smoke or duplicate stuff.
