How to import and use .glb files in your game-engine.

I don't make games, but I check my models primarily for artifacts, UV issues etc.

Here's how I do it at the moment:

Godot (I follow these routines from the Godot community):

1. For importing glb: Godot 4: Importing 3D Models

2. For LOD settings: Godot 4 Automatic LOD Tutorial

Unreal 5 (options: import in Content Browser, or drag and drop, or use Import into Level):

1. In my case I go to Content Browser, create a folder and name it Models.
2. while in Models, I hit Import and select my glb files. 

3. in the Import Content dialog I uncheck the following:

   • under Common Meshes -> Build, unchecking Recompute Tangents.
   • under Static Meshes -> Build, unchecking Build Nanite.
     (these settings are not necessary for my own checking, however, I assume you know your way around LODs and stuff in UE5. I leave you to it.)

4. after import I'm then able to drag a mesh on to the level.

Unity 6:

1. open the Package Manager, and click the + button and select Install Package by Name.

2. type in com.unity.cloud.gltfast and press Install, and wait for it to complete.

3. I usually create a folder called Models inside Assets

4. while in Models, I browse to my glb files and drag them in to the folder pane

5. and then I drag them on to the scene.
