A black spot shown in the screen when Play??

You need to give more information on your project and that level. It may be the sphere mesh of the default spectator pawn but i’m not sure.

It is spectate pawn. On begin play you are activating camera actor and it means you are disabling default pawn. and this pawn is that black object on your camera. There is some solutions.

  1. try to set player start position on different location (not front of camera).
  2. try to change default pawn and create that pawn which will not contain colliders and meshes.
