gltf file not showing in Aframe

I have two files, an glTF and OBJ file. I'm using Glitch to develop and I uploaded both of them to my assets folder.

When I read my marker, only the OBJ file is displayed.

        </a-marker>

I don't get any errors in my console. Is just not showing up.

Solution

If you open up the .gltf file - you will find the .bin and textures are referenced with relative file paths.

The glitch "assets" folder is not a real directory - the files within have different paths, that possibly are nowhere near each other.

Try:

Converting your model to .glb which just contains all resources and dependancies
Throwing the model on a github repository, where paths are relative
Editing the .gltf file by replacing the .bin, and texture paths with glitch asset links.
