how do you do your background image?

do you put in max enviroment, background image or after in photoshop?

Either way works, you can also do it in Max thn save your renders with alpha channels and replace the background later in Photoshop if you want to. I usually put something in the Max background, if only to double as the reflect/refract environment (HDRIs are best for that) and use PNG with alpha channel.
