Today I decided to record a video walking you through everything you'll need to know to create your own time trials in BeamNG.drive. If you have any questions/suggestions, let me know in the comments below!
The file path you will need to create for your .zip file to share your time trial is:
modname.zip\gameplay\missions\*mapname*\timeTrial\yourFolderGoesHere
You can send this .zip file to your friends and have them drop it into their mods folder, and then once the mod is activated, the time trial should appear in their game for you to compete with one another.
