Godot Version
Godot 4.0
Question
Using Blender 3.0.0
The problem was that I was Rotating the Map in Blender by -90 Degrees, on the X axis, to align with Godot’s Z+ Forward, rather than Blender’s Y+ Forward.
This caused the Glitch.
Solution: Never Rotate the Map Before Importing to Godot, to align with Godots Z+.
Every single time I was applying all transforms before import,
making sure everything was Fine.
So this simple -90 Rotation caused the Camera Glitch,
where you become the Camera Itself, rather than the Player.
