Some of our options for reflections in future versions of Lumion:
Object reflections (for product visualisations):
As you know we currently only have a single 360 degree reflection map in Lumion which all reflective objects use. This is not a one-size-fits-all solution which is why we're getting so many questions/requests about reflections in the forum.
Remko has previously mentioned that it might be possible to render additional 360 degree reflection textures for individual objects. Each texture would have to be rendered from the centre of each object, and this technique would make the reflection approximation more accurate. If the reflection textures were updated in every frame, it would however take its toll on render times, so if this were to be implemented we would probably have to make it possible to switch off dynamic updates for those reflection textures.
Planar reflections for water, reflective floors, mirrors etc:
This is a proven technique, but the downside is that you have to render everything that is reflected a second time (mirrored), and depending on the scene complexity this can drastically reduce performance. This is the reason you typically only see planar reflections in small scenes in real-time 3D graphics.
