The example scene TexturePlane uses these for external prototype instances and creates a plane with one of a set of textures mapped to it. The texture choice is controlled by a fraction eventIn. SlidingPlane creates a texture plane that slides back and forth along the X axis, changing the texture based upon the X position.'/> |
