With the Chrome Lib, graphic artists are empowered to create FX and interactive scenes by themselves, without the need to resort to programming. The Chrome Lib has also been designed to help Shockwave 3D developers tap into the potential of the engine. The Chrome Lib makes for the lack of 3D timeline in Director to interpolate transforms or tween material properties such as the emissive color or the blend level. UI behaviors display 2D user interface components on top of 3D and control the 3D scene.
