I was attempting to upload my first entry into the Looking Glass importer challenge but have been unable to get it to upload in gltf format. Currently I have uploaded it in .blend format.
Any time I attempt to upload a gltf version of it, I get an error code 13 file invalid. Even when attempting to upload the gltf converted by Sketchfab’s own downloader. Has anyone run into this problem before? Does this have something to do with it being animated?
