For stage design: some spotlights will create a beam effect (Dundar), but other lights are not needed. Fog and Tyndall Effect will fog all lights in version 2.0
The stage design industry needs D5 like 3Dmax, which can allow the Dundar effect to pick the light source. Currently, lumion and other real-time renderers have not been developed for this function, we hope that D5 can be the first to update this function.
