Changing "Lighting Data Asset" at runtime?

Hello,

is there a way to change the "Lighting Data Asset" after or before a scene is loaded?

I have several baked lightmaps, but only switching the lightmaps dosn't work.
It works only, when i use the right Lighting Data Asset.

thx for help

 

I'm interested too anyone can help us ?
Thanks in advance

 

me too need help

 

Is there really no way to use different lightmaps for a scene where some static objects are different (in Unity5)
Do I really need to create different scenes for all little changes in one scene?
You can't be serious

This is a bis step backwards from U4 to U5

 

I need help too！Still no solution?

 

Lightmapping.lightingDataAsset = Resources.Load ("Map 1 - Sun/LightingData", typeof(LightingDataAsset)) as LightingDataAsset;

Funny think is that this line work in the editor but when building for android it gives me
The name 'LightingDataAsset' does not denote a valid type ('not found'). Did you mean 'UnityEngine.LocationServiceStatus'?


So you still can't change the lightingDataAsset via script?

 

It can't be found because it's part of the UnityEditor namespace. (https://docs.unity3d.com/ScriptReference/LightingDataAsset.html)
That namespace isn't available for builds.

 

any chance of ever getting this mess sorted out? I have one scene and various rooms that I want to apply lighting to when I switch between them. Why on earth would anyone think that being restricted to one light map per scene is remotely sensible, and why make it close to impossible to manually swap light maps? This has become a real problem on my project so any short term suggestion for a fix would be appreciated

 

Hello Is there actual way to change Lightnig Data Asset for scene on runtime? I'm using realtime GI precomputed only and I need possiblity to change lightning data asset in runtime not only by drag and drop in editor

 

Have you solved this problem？（Changing "Lighting Data Asset" at runtime?）

 

The lighting data asset is effectively just a collection of data that gets assigned to renderers when the scene loads (refer to https://github.com/NewBloodInteractive/com.newblood.lightdata for information on its structure). There's nothing preventing you from storing that data somewhere at runtime and recreating that functionality.

After you assign new values to LightmapSettings.lightmaps and LightmapSettings.lightmapsMode, you then just need to iterate over all of your lightmapped renderers and assign the appropriate lightmapIndex and lightmapScaleOffset values (which is exactly what Unity does when it loads the lighting data asset).

 

How do you use C# to reback the Probes Light Data (likes LightProbesGroup) and restore these Probes ? Dynamic object need these lights(But real lights),Unity2019.3 or New

 

Light probes are unfortunately the one part that you can't reassign at runtime. You'd need to create your own light probe system and use https://docs.unity3d.com/ScriptReference/MaterialPropertyBlock.CopySHCoefficientArraysFrom.html to assign the lighting to renderers.

 

Thank's.But that looks like trouble.I give up the LightProbesGroup,using some real lights

 

Does it mean that in Unity today, it is not possible to set all light environments by loading and applying template scene assets and light-related data created in another scene?

 

You Can Use Magic Lightmap Switcher (Storing, Switching and Blending Lightmaps in Real-Time)

https://docs.unity3d.com/ScriptReference/LightProbes-bakedProbes.html - This doc is partially helpful, works for directional lights.
There is a workaround, you can save all light settings to an empty scene and then you can load that scene as 'additive'.
