Reflections
In the real world all objects exhibit some degree of reflectivity based on surface shine,
brightness, angle of view, and proximity to reflected objects. Motion simulates this natural
effect, equipping every object with a set of parameters to create and control
realistic-looking reflections. When Reflections are enabled for an object, all other objects
in the scene are reflected but may only be visible from specific angles and distances.
Reflection Parameters
The Properties Inspector includes a Reflection section.
Reflections Parameters in the Properties Inspector:
Reflection: This checkbox enables reflections based on the settings of the parameters in
the group. (When selected, the checkbox turns blue.)
Reflectivity: This slider controls how shiny the object’s surface appears. 0% indicates no
reflectivity, while 100% is perfectly reflective, like a mirror.
Blur Amount: This slider controls whether real reflections appear in sharp focus or quite
blurry, depending on the surface quality of the reflecting object.
