Solution: This problem can be avoided by turning off Two-Point Perspective and rendering again.
Fog and Dundar effects, when turned on, apply to all lights in the scene, which is inconvenient… Especially in the stage lighting design industry, only certain spotlights need to project beams.
It is recommended to bind the Dundar effect/fog to specific light sources
According to the Lumion12 trailer, we can see that this feature is coming in November (which is also the most important update we can see in the Lumion trailer), D5 should be developed before Lumion (by November), it will occupy more market, time is of the essence
This feature will definitely come in the next version of D5.
