Disable Lighting for 2D games

Hi, I’m new to Unreal Engine. I’m learning the engine by making a simple 2D game.

I want to know if I can disable lighting for 2D games so that the graphics appear as intended (like in the Unlit mode). Currently, the game renders in Lit mode by default.

I placed just a Sprite in the world and found it brighter than it should be in Lit mode. I disabled Auto Exposure, Bloom, Ambient Occlusion, and Lens Flare and tried to tweak the Auto Exposure Bias (I’m surprised that the Sprite even reacted to the changes despite Auto Exposure turned off), but I can’t get close to the Unlit mode.

I have tried as many approaches as I can find, but to no avail. I’m wondering what I missed because creating 2D games should be easy.

Appreciate it if anyone can help.
