Ok, I think I have reproduced the issue that isolated to the Editor itself when switching from an actor locked to the viewport to the perspective camera.
Here’s my repro:
- Create a new map and add a camera to it
- Look through the camera
- Move the camera interactively
- Save
- Switch to the perspective camera.
RESULT: The map is marked dirty as you can see an asterisk at the top where the name of the map it.
EXPECTED: The map is not marked dirty since you’re just switching to the perspective camera and there hasn’t been a change to the transform.
I’ll file a bug with the editor team and if the bug is accepted, I’ll report back here with the public issue you can track.
