who would be adorable enough to share a court map that works ??? 
Don’t work i test all (without make per GTA V éditor map ) but tanks 
Maybe try using ymap. You need to setup the resources but should work once the resource is setup.
All maps that are from the site Akira posted should work as long as they don’t require map builder props, but I believe there is a resource that will stream those to the server that will make it work but the file also needs to be in a .ymap format and making sure you have this_is_a_map 'yes'
