Error Message about lightmap and ambient settings

Hello, when I select World Designer from Hierarchy, the following error pops up:

Setting up default lightmap and ambient settings had a issue Object reference not set to an instance of an object This came from   at Gaia.GaiaLighting.SetDefaultAmbientLight (Gaia.GaiaLightingProfile profile) [0x00098] in My project address\Assets\Procedural Worlds\Packages - Install\Gaia\Scripts\Editor\Lighting System\GaiaLighting.cs:1426

Can you please tell me what Gaia version and Unity version you are using? 
Example Gaia Pro 2023 4.0.7 Unity 2023.1.X

[WeitingTu]

Sure! The Gaia Version I'm on is Gaia Pro 2023 4.0.4-c5 and the Unity version is 2022.3.12f1

Hi @WeitingTu,

I looked into this error and it seems like this might be an issue with the Lighting settings asset found under Window > Rendering > Lighting here:



Normally, if there is already a Lighting settings object in this slot, Gaia should take this one. If the slot is empty in your scene, Gaia should create a new settings object called "Gaia Lighting Settings" for you. It looks like in your scene there is a problem with that lighting settings asset. Could you please check if there is one in there, or if it is maybe a missing reference?
If this does not give any new insights, could you please try to create a new lighting settings asset yourself before you select the World Designer in the Hierarchy?

[WeitingTu]

Hi @Peter
Thanks for the advice.
I've checked the Lighting Settings there and there's already one called Gaia Lighting Settings in the slot.
I still proceed to create a new one and replace it but the same error appears, is there any other place I can check?

Hi @WeitingTu, thanks for checking this! I noticed that the error message visible in the console seems to be a different one, it now reads
"Setting post processing enable/disable state had an issue", the original error was
"Setting up default lightmap and ambient settings had a issue"
If this is really a new error message, it means using a new lighting settings object was successful and it now has an additional issue. Could you please send the full error message for the Setting post processing enable/disable state had an issue error as well?

[WeitingTu]

Hi @Peter, sure thing! here's the entire error log, thanks for helping me out!

[Peter]

Hi @WeitingTu, I had a look at this newer error, and it is really strange, it looks like it is running into an error in an older function that is a leftover from Gaia 2021, but is not really used anymore. I created a patch for you that removes that function, can you please test if this works for you?

GaiaPostProcessingHotfix.zip

 

You can install the contained unitypackage via Assets > Import Package > Custom Package in the Unity Editor.

If the fix does work, this change will be added to Gaia oficially.

@PeterThanks for the package! The error stop popping up after the install!
