Thank you ;)

I used BakedLightmaps for all levels - it precalculates indirect lighting in the editor so you have fast GI at runtime. It makes the environment less dynamic, but for most games that's not an issue. I also always used a sky (procedural Godot sky but HDRI skies work as well) even if it's not visible indoors. This creates a more realitic lighting in combination with the baked lighting. Then i added one or two Omni/Directional lights per scene. If you use GLES3 you can also change the Tonemapping to something other than Linaer...i used GLES2 so that was not available unfortunately.

For the gun i baked an ambient occlusion map in Blender..otherwise it would have looked a bit too flat without textures. Standard Godot materials support ambient occlusion maps.

Thanks for the reply! I wondered if it was baked lighting. I still haven't gotten around to learning how to use it. I wanted to use it for my currently game jam game, but got a little intimidated by setting up UVs. I typically texture my 3D art by creating a color palette and just kind of crushing the UVs into the color I want.

I didn't know more than one directional light could be used. That is interesting!

You don't have to setup up UVs manually if you want to use BakedLightmaps. Godot generates the UVs for lightmaps automatically on import (there is a setting in the import tab). They are called UV2 and exist seperated from the normal UVs you create in Blender.

That's good to know! I didn't realize Godot would generate UVs. I assumed that the UV2 slot would just be a copy of the regular UVs, which in my case  would probably be too compressed to have good looking light maps.

The other concern I had is that all of the assets in my game, minus the enemies and some glass, all use the exact same SpatialMaterial. I wasn't sure if that would cause an issue either.

I'll give this a try next time I have the chance! Thank you. :)

No that's not a problem. You can use baked lightmaps even if you only use one material. You're welcome ;)
