Question about render target/scenecapture

Hi,

I am trying to create a mini map for my game.

Here are my steps on creating this

  1. get render target ,
  2. Create a material set the mat box to interface
  3. plug in to base color
  4. add a camera above the player with scene capture attached to camera
  5. Add image to a widget for a HUD
  6. Use material for image.

I compiled and played but when save and quit the engine and open it later, the perspective view gets messed up. It looks like the camera above the player takes over.

Happens is 4.17.2 and 4.18 too

Why?
