MeshRenderer shadows and lighting performance when there are no lights

Unity Engine
1

I’m making a 2D game and on every sprite, naturally, there is a MeshRenderer. The MeshRenderer component has lots of options relating to lights and casting/receiving shadows. I have no lights in my scene so my assumption is that leaving all of these switched on will have no effect on performance - is that right?

I could go through each scene and switch them all off if I have to I guess, the sprites all look the same whether I have all the settings on or off.

They should have SpriteRenderers on them, what version of unity are you using? But yes, have cast/receive shadows on most likely will affect performance because it will be checking for lights and trying to cast shadows.

Silly me, I should I said I was using 2DToolkit. I’m using Unity 5.4.0b7

Odd that it would try and cast shadows if there are no light sources, but ok.
