Amazing work! Hey since RD doesn't allow posting of a lot of these tracks. Can I recommend you just post the links to them in your YouTube videos so we don't have to go searching for them? Thanks!
Geo location for Jeddah in "ui_track.json" is
["21° 38' 16" N", "39° 06' 09" E"]
Great work. It would be great if wall textures have collisions in an update, or is it something I have to activate in a text file somewhere?
