This is basically the green-screening technique that everyone uses. Have a one color background, anything covering the background in a ridiculous color works, like the usual lime green or something like that, the more it differs from the colors of the character the better. Don't film outside because the time of day will affect the way sprites look.Ģ. This is to make sure that all sprites in the same sheet and across different characters looks consistent. In other words, use artificial light preferably.
I'll start by adding more detail to what raoniluna said, since it's really good feedback.ġ.
