Hey guys, I was trying to load a gltf file and merge the meshes.  
Loading is complete but the merge throws an error in console: “Uncaught (in promise) Error: Positions are required”  
This is the demo: [Babylon.js Playground](https://playground.babylonjs.com/#7H7F1Z)  
I appreciate any help, link on documentation etc.  
Thank you

Hello and welcome!

This is because all meshes are not with geometry: [https://playground.babylonjs.com/#7H7F1Z#2](https://playground.babylonjs.com/#7H7F1Z#2)

Cool thank you for the support!  
I’ve obtained this gltf converting an obj file with obj2gltf. As with merging of obj meshes I had non issues I was expecting the same for gltf file
