| − | Billboards are commonly used for particles, far away [[Category:EnvironmentFoliage|trees]], [[GrassTechnique|grass]], clouds, [[Category:UserInterface|UI elements]], etc. This is a common device to get more detail in objects without using a lot of polygons. However, they are flat and may look strange when you move around them.

| − | Billboards can be set up to rotate on only one [[RotationalAxis|axis]] or on combinations of axes. For example, a tree might be set to rotate only on its vertical axis, so it always appears grounded. However a puff of smoke usually looks better if it always stays upright and flat to the view.

| − | One cool trick is to use a curved billboard, which helps give more depth to a single-axis billboard, because like a tree billboard, you can look down on it, so the extra depth helps get rid of that flat look.
