2D sprite render component for Classic DooM style sprites for Unreal Engine 4 and 5.
Take the component UE5.1/2DSpriteRender and add it to the pawn that you'd like to make 2D. The component will do the rest, spawning the plane actor and setting the rendertargets. Also contains PP material for old 16-bit pixelated look.
This is an outdated but usable version if you are still using Unreal Engine 4. Take the component UE4.26/2DSpriteRender, BP should be pretty much self explanatory.
