No light after the project loads

a.drexler · July 21, 2026, 10:18am

Hello,
After loading a project created in V3.1,
the light is missing.

If I select a different scene, everything works fine in that one.
But when I go back to the first scene, the light is on there, too.
Most of the time, anyway—not always.

This is some weird behavior from V3.1.

I have a PC with an RTX 5090 and 64 GB of RAM; the current graphics driver is 610.74.

Bye
Andreas

Hi @a.drexler

From what I understood from your description:

Opening the scene will result in a nighttime view (where the main light source disappears)
After switching to a different scene and then going back to the first one, it will revert back to its original view
And this always occurs in every file that you have? Or only to this specific one?

Which specific version are you running? Can you send us a screenshot?
2.11 Build Version

It might also be best to include a video-recording showing the whole issue.
Please send us your D5 File along with your log files.

Hi @a.drexler

Are you able to send this file to us?

I have tested your file with the 3.1 hotfix, and it has already been resolved. Currently, the hotfix is in grayscale release; you may have received an update notification already. If not, please wait for the official release.
