Its a small file , 473kb … upload is fast , stuck on processing forever… closed the scene and tried again , same thing.
In the console it is spamming :
commons-e28186ad6fe8b65eacca.js:56 XHR finished loading: GET “https://sketchfab.com/i/environments/98d05156f8d8457bad2b0e23908cf88b/status”.
The part between “environments/…blahblah…/status” keeps changing it is spamming a new one every second to the console…
EDIT: I tried resizing the dimensions now even to power 2 sizes … still the same issue , stuck processing … spamming the console with the same messages
