I tried disabling the auto exposure by following this tutorial and creating a PostProcessVoulme. It did reduce the overall light but the ambient light still remains.
The scene only contains a cube and 6 planes completely encapsulating the cube along with the PostProcessVolume added to disable auto exposure. The scene doesn’t have any skylight, HDR image, or reflection capture actor.
How can I remove this ambient lighting completely?
First of all planes “does not cast” a shadow, or at least not tho ones looking to the camera. Because the shadows are generated by normals, and if you put a plane and look behind it will be transparent, meaning that the light will pass.
For this case the best is to use cubes, that have 6 faces.
Now for the lightning problem itself, it’s hard to say why it is still iluminated if there is no lights in scene, but what I’ll do is to make a Post Process Volume and not deactivate the Auto exposure, but I would set the Exposure Compensation a negative number.
That way the scene would be seen with less light, even if there was any.
Here for example, I put a Post Process with Exposure Compensation of -4.
