Hi,

Running physics on dedicated server from PIE or in standalone(project.exe -server) gives me different results.

Please see attached project. Steps to replicate:

PIE:

1. Run game from editor in Dedicated Server mode. Pawn is levitating, there is force applied to counteract gravity. Nice and easy, this is expected behavior.

Standalone:

1. Run project in server mode. (-server flag)
2. Run project in client mode (-game flag)
3. Connect to server from client (in console “open 127.0.0.1”)
4. Pawn is receiving approx twice as much force as in PIE mode. Flying away! Why?

I am suspecting that server is applying force twice as often as it should ( I expect just once per tick). I havent prove it yet, hoping to get some help from you guys.

Any suggestions ?

Thanks! Would it be possible to have developers evaluate it and provide a workaround if its possible ?
