Billboard behavior

The Billboard behavior automatically rotates an object to point towards the camera. It is generally used with the 3D camera object, and is often useful with 2D objects like Sprite to make them always appear flat against the camera with a 3D view.

There are alternative ways to achieve a billboard-style appearance without using this behavior. See the Billboard styles example for a demonstration.

Scripting

When using JavaScript or TypeScript coding, the features of this behavior can be accessed via the IBillboardBehaviorInstance script interface.
