I tested the [Material Combiner addon](https://github.com/Grim-es/material-combiner-addon)  
in Blender to create a Texture Atlas, and the results are great.  
Before, each player used 2–6 materials which caused many draw calls.  
Now each player has only one material.

**Benefits:**

Greatly reduced draw calls.  
Higher performance (my FPS went up by ~50 with 25 players).  
Cleaner glTF/GLB files, easier to load in CGE.

In short: using a Texture Atlas = fewer materials = fewer draw calls = better performance.

@Michalis: maybe it would be useful to mention this tool (or texture atlas workflow in general) in the CGE optimization guide  
, if nothing similar is already documented there.
