The demo shows a cubemap texture used on a skybox and as a reflection map on an object.
You have a choice of two textures and six objects. The "Base Color" radio buttons change the
color of the object. The color is multiplied by the reflection map, which adds a tint to the
reflection. The colors that are used on the object are only a little different from white.
Note that the object does not really reflect its environment in the scene. It only looks
like it does because the same texture is used on the skybox and for reflection map on the
object. The radio buttons above the scene let you choose to see just the skybox, just the object,
or both. Note that the object shows the same reflection whether the skybox is there or not.
Drag your mouse on the canvas to rotate the scene.
