I am trying to animate a simple graph. The shape begins as one large triangle. The triangle then breaks apart into four smaller triangles. These triangles drift upwards, and each spins slowly to a different position, before all come together as one large tirangle again.
As they drift up, however, they need to leave some sort of trail. The trail needs to appear as they raise up into the air behind them, then dissappear when they come to rest.
The animation of each object is simple, but does anyone have any suggestions how I night simulate a trail effect?
