Hey, Lightmap GI don’t work on mobile in 4.4 beta or it don’t work at all whatever the version used?

What OS and GPU are you baking the lightmaps on? What mobile device are you exporting the project to? Without any information, it’s hard to know what’s causing the issue exactly.

Also, can you reproduce this in a brand new project (and upload the project in question here)? Do your meshes have UV2 generated on import by setting the GI mode to Static Lightmaps in the Import dock?

Lightmap baking works on all rendering methods, but you need a GPU that supports Vulkan if baking from Compatibility. Note that there were some regressions in 4.4.beta but these should be fixed in 4.4.beta4.

Hello, sorry for my late response, i was really busy this last week.

I thought at first that light baking wasn’t available for phones, but if you are saying that it is possible, then there is a real issue.

I’ve made a test scene with godot 4.4 rc1, with mobile renderer, and baking the light works just fine, running the project on pc also works, but when it comes to my phone, the application closes instantly.

Here the github repo for the project: GitHub - Dams4K/TestBakingOnMobile

And ofc, I’ve selected Static Lightmaps for the 3d model (else it woudn’t work on pc)

Edit: my phone is a Samsung S21 FE using android 14

Try changing the lightmap texture (world.exr)'s compress mode to Lossless in the Import dock, reimport it and export the project again.

Yeah, but godot should be able to bake light for mobile, baking is just textures. If you really need to bake lights for your project, maybe you can with blender

edit: Lightmap GI is working with godot 4.3 so you can still use this version, if you use beta versions or even candidate versions, you’ll always find bugs.
