How To Change Play Style From 3D to 2D or 2.5. When Hitting Trigger

I’m making a 3D platformeing game, but I have a section where you wall jump in order to collect collectibles. I set a camera and a trigger so it’s easier to see when scaling the wall. But my controls are still locked as if im playing in a 3D Behind the back play style. I’m just trying to figure out how to change my controls for a 2D segment like that, so I move left and right. Any help would be much appreciated.

Create a trigger that will change the rotation of your camera spring arm(should be always 90 degrees to get the 2D effect), disable mouse control to the camera that way it will be stuck to one plane, play with Inherit Pitch, Yaw, Roll that way the camera won’t move as the character rotates and add character movement from camera direction and not the player. Good luck.
