Scenemanagement loadlevel and Enlighten

Hi,
i don´t get it.

Scenario: I am planning to have a rather empty app. Content will be loaded from online via Assetbundles.
Some Assetbundles hold just 3Dmodels and Shaders, but others hold a whole scene including lighting information. This involves having skydomes, all the baking info such as light maps, reflection maps etc.

So i have my base app. I t downloads a JSON file with references to assetbundles. All this works.
I planned to have a some rather empty scenes in the base app. Only holding a camera and scripts to additionally load a bundle with a complete scene. Those two scenes should merge. (Its a VR App targeting Cardboard for now). The main apps scene has a special camera setup for VR (having a reticle and scripts for VR) but absolutely no lighting info - as there is nothing.

It loads successfully a bundle with full lighting info (and on top of that Postprocessing stack v2).
However after loading this, i have of course two cameras. The one from main scene and then a new one from the loaded scene (which holds the post processing stuff)

Problem: i cannot get the lighting info from the bundle scene to take over.
If i load it with LoadSceneMode.Single -> Yes then the lighting info and skydome are there. But of course my VR Camera is lost as the calling scene gets deleted.

If i load it with LoadSceneMode.Additive -> Then the lighting info might be there, but defiantly not the skydome associated to the bundles lighting info.

I also tried merging the scenes and find Cameras - then delete the one or the other camera.
But no matter what i do, something breaks. Either i have no sikydome from the asset bundle and no lighting info from it as well as no Postprocessing - or i have it but los my VR Camera.

In short: I lack the understandanding of loading Scenes additionally and decide which scenes lighting info to use and how,


Sounds complicated? Yes it is.


And no, i don´t want to put everything in one project - the planned project would be to huge and only asset bundles could help.

 

Have you tried setting the newly loaded scene as the active scene? The docs are limited, but I believe the active scene's lighting settings take over the previous scene when the new scene is set active. Note that any newly instantiated gameobjects become part of whatever scene is active by default.
