Tilt Brush / Gravity Sketch: "Lonely Planet"

Description

I was inspired by "Dune", the SF-series; you might have heard of it. So I made this scene in Tilt Brush and also added a few Gravity Sketch buildings as objects which don't seem to show up however after being exported to Sketchfab. Any suggestions would be welcome. The YouTube-video of this scene, including the Gravity Sketch objects, is here: https://youtu.be/WNlfQItOd8Q,
