is there a way to stop the lighting dimming slightly whenever a character moves across the map via a teleport?

so I want to set up a seemless teleport to create impossible geometry corridors that loop on themselves but whenever the character teleports between corridors the lighting seems to dim very slightly meaning it’s not quite seemless, I have a post process volume set up with motion blur turned to 0, the min and max exposure EV100s are set to 1, and the lighting used in the level is a grey ambient cubemap, any advice?
