Topic: Light not updating in Lumion

[pablo102]

I have an animation with moving camera and sun study effect on.
The sun is set up to night on the beginning of the animation and through few keyframes it ends on 12.00.
So there is a significant change of lighting during the video.
While exporting to movie the effect will not update correctly smooth in realtime. When I press U it's adjusting the scene, but it should do that automatically. What am I missing here?

Hi pablo102

What version of Lumion v4 are you using?

Can you post a sample video of the problem.

If you start the hour at more than 12 for night and end at 12 noon the keyframes will result in the animation working backwards.  This is a current limitation in the keyframe options for the Sun Study and have been noted.  You can only work forward, for example 12 noon to 24 midnight.
