How would I disable ambient lighting in a 2D project?

Hello

For about a week now i’ve been working on my 2D project which involves particles and my goal is to try making a pitch black so the particles and cube which they emit from emit light. I’ve searched for ways to disable ambient lighting and did all the steps but every time I do they wont work. I think its just me not looking in the right place but it still could be something else in Unity. I have no lights at all and ambient color is set to pure black.

Hi,

I have the same problem, in a 2D project without any light and I have no intention to use light engine (Enlighten) but looking Profiler I can see how Global Illumination section has work. Is it not possible to totally deactivate light engine?
