Another noob question,
I used the GLTF export addon for blender , I also set all the materials to use the metallic roughness group in the nodes exactly as shown in the docs :
But when I load this model, via the loader class in my own experiments or even via drag and drop in the sandbox, no materials are loaded … everything is just the same grey color. As can be seen in the screenshot my one material should be red. I double checked the export options and “export materials” is checked.
Any clues why no materials load? ( im exporting glb )
