FIRE is able to display Floating Shadows and Floating Reflections of your objects on the ground, even without a geometry ground plane in the scene. This feature is very helpful during the design stage or even for presentations of your products, as it quickly provides a nice preview of your models even at an early stage. To turn this feature on in FIRE you simply have to enable the Floating Shadows and/or Floating Reflections checkboxes in the FIRE properties tab. It is worth remarking that the floating shadows are actually cast from the emitters in the scene, respecting their geometric characteristics and material settings, and so the shadow render is accurate. With this feature it is easy to show an object over a solid color background while producing reflections and shadows in the ground.
