Static lightning and 2D games, is it needed?

I noticed if I tick “allow static lightning” under rendering options my game size jumps up nearly 2MB.

I’m not noticing any performance differences by leaving it unticked. Everything is unlit or transparent unlit sprites. There is the exception of HUD items which use the shadow setting on fonts; not sure if that’s lighting related.


The HUD shadow is not lighting related, it’s just a simple 2D effect.

Hey if i may ask. My game is a arcade 2D game however its not a game that uses sprite. I don’t use any Static lightning because it’s not needed at all. The game is only black and white but i am also planning to add the color red to one of my 2D static meshes. When i implement it to my level it’s just black even though the colors red. Actually everything is black mostly because there is no lighting. I don’t want to put lighting in my game because it’s not needed but i want to be able to see different colors. Is there a solution to this. Sorry for the stupid question.

The gaming technology can be made more attractive through some special efforts and 2D imaging.
