Sphere instead of transport, car

Good day. I wanted to play with a friend in beammp on their server, but there was an unexpected problem - when I go to a friend’s server, I see a sphere instead of a friend’s transport, and after I go back to the other side, he sees me as a sphere.

You are using vehicles that are not installed to the server. The reason why BeamMP disables all your mods when you start it is because client side mods do not work in game, any mods that you want to use need to be installed on the server side.
