The lightning of Preload Scene is not working after update

in Technical Help (nuts n bolts)

Hello

When I used Daz Studio 4.15. one of my favorite environments worked without any problems. I could just open it, insert my characters and the lightning was perfect. The lightning was similar to the preview images on the product page:

Now after the update to Daz Studio 4.22 the scene can be loaded but the lightning is bad. It has gotten dark, see attached picture. I could try to light up the scene manually but I would love if there is an easier solution for that, so that my preload scene works with lightning. Since this is only an example because there are also other environments which have changed lightning after the update, it would be great to find a solution or explanation.

Does somebody have an idea what went wrong and what could be done. I can't find a solution.

    My guess is it uses ghost lights, and the behavior of ghost light was changed.

    If so, you could update them to a newer version of ghost lights https://www.daz3d.com/forums/discussion/609556/creating-a-ghost-light-daz-studio-4-21-1-26#latest

    Because a couple of  "bug version" ghost lights are used in this product (back to the time of DS 4.14/4.15).  Nvidia completely fixed this bug around the time when 4.21 was released ...

    So, with 4.22, the quickest way is to tweak the settings on that ghost light surface, as well as some finetune in Tone Mapping. See below screenshot.

    Or, check this thread: https://www.daz3d.com/forums/discussion/609556/creating-a-ghost-light-daz-studio-4-21-1-26#latest to make a "new ghost light" for this scene...

    Thank both of you for your quick help. Now that I know where the problem comes from I can do something. I learned that the ghost light problem is a massive change and it is sad that it affects one of my favorite scenes.

    Thank you very much for the example scene with the made changes which brings it close to the original lightning. This was very helpful.
