This is a very simple plugin which will allow you to walk your UMmus around on the surface of planets in Orbiter 2016. This is not a full compatibility patch by any means, and rather just a quick bandaid fix for those who are really keen to get their UMmus walking around. Check the readme for keyboard controls.
The plugin *should* also work to stop UCGO cargos flying off at ludicrous speeds when dropped too, but I could only achieve intermittent success with this.
Unfortunately this does not fix UCGO cars at all.
If people like this I may consider working on this further to fix more issues.
Please let me know if there are any bugs (besides already known UMmu3.0 in Orbiter 2016 ones), and if anyone would like the source for this just DM me on the forum.
Happy Orbiting,
