Blank project fail render for client0 in multiplayer

Hey, I’ve created a blank project, with absolutely no modifications, and run a multiplayer session, my params are:

  • “run under one process” unchecked
  • 4 clients
  • run as client
  • new Editor window (PIE)

I don’t know why but the client0 always has a failed rendering of the scene, it renders objects but not the floor: Any idea?

If I tick “run under one process” all clients fail to render.

According to Authaer on Unreal Slackers, it happens because the initialization in the editor extension performs extra steps compared to a standalone process initialization.

To fix it, I need to run everything as a Standalone process (under Modes, and under Net modes). But in theory, it should not happen.
