How do SpeedRay Reflections work?

There are three different reflection types in Lumion:
  • Planar reflections: Very accurate on planar surfaces but renders slowly.
  • SpeedRay Reflections: Mostly accurate on any surface and renders fast.
  • Projected Reflections: Not very accurate on any surface but renders very fast.

SpeedRay Reflections are available via the Reflection effect in Lumion Pro:

Version 8 and above: Movie/Photo Modes FX -> Add Effect -> Light & Shadow tab -> Reflection

Versions prior to V8: Movie/Photo mode -> New effect -> World tab -> Reflection

Materials that have Reflectivity and Gloss will reflect the local environment. This creates a much more accurate and defined reflection on any surface. This setting is a lot faster to render than Planar Reflections (via the Reflection effect) but slightly slower to render than Projected Reflections. The reflection can apply to any surface as well as to planar surfaces.

Use the Gloss slider of materials to adjust the amount of blurriness in the reflection.

You do not need to add any planar surfaces to enable this reflection type to work - just include the effect and turn on the setting. Any surfaces selected for planar reflections will continue to be rendered as fully planar reflections, even if SpeedRay Reflections are turned on.

Please note that SpeedRay Reflections can only reflect what's visible on the screen. If a reflective material is facing an area outside the field of view of the camera, the least accurate reflection type, i.e. 'Projected Reflections' will be blended in.
