Blender can export custom properties into a gltf/glb file. Is there any way to acess these in babylon? Mesh.metadata doesn’t contain them. ---

Let me invoke our Blender Grandmaster @JCPalmer ---

Maybe @Vinc3r knows, but not actually a BJS question until they are actually in the file. First, does gltf even have custom property / metadata storage? If yes, then does the Blender implement it? For that I would go to the Blender / Khronos [repo](https://github.com/KhronosGroup/glTF-Blender-IO) If yes, ask if / how it is implemented in the loader. ---

@JCPalmer Blender does support this., the Khronos exporter as well. ([Added support to export custom properties/extras. · KhronosGroup/glTF-Blender-Exporter@0835c60 · GitHub](https://github.com/KhronosGroup/glTF-Blender-Exporter/commit/0835c60fffb153a0c4563c35ab72044bc5830d37)) Would you be open to a pr for this if it is not implemented in the loader yet? This would be very handy for e.g. storing information about collision shapes (whether its a box, sphere, etc) or physics data like the mass of an object. ---

I did not write the glft loader in BJS. Think @Deltakosh flagged me because of Blender, back to him. @mauricedoepke, I would create a simple plane, add a value like ‘I AM ALIVE’ for the custom property, then export in the text format. You could then post the tiny file here, and ask why not , or where this is in the loaded scene. ---

Pinging @bghgary but I do think we expose it ---

[3dsmax export to .gltf with tags](https://forum.babylonjs.com/t/3dsmax-export-to-gltf-with-tags/686/11) links to a PG that adds a custom loader extension to read extras properties. You can do something similar for whatever extras you are exporting. ---
