More info See in Glossary.Īmbient light can be useful in a number of cases, depending upon your chosen art style. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. Think of each unique Scene file as a unique level. It can be an important contributor to the overall look and brightness of a scene A Scene contains the environments and menus of your game. Therefore I think 1) is the better solution.Ambient light, also known as diffuse environmental light, is light that is present all around the Scene and doesn’t come from any specific source object. My guess is that the current behavior is preferred by most people simply because it is more realistic but that is just a gut feeling. we change the behavior of the lightmapper so that 'Environment Light' (as it is called in the Lighting UI) affects lightmapped objects like it affects dynamic objects (no blocking of light).

Unity ambient light update#

We update the current behavior to reflect the manual.

we make it clear that 'Ambient Light' can mean different things depending on how you light an object.

Unity ambient light manual#

We update the manual to reflect the current behavior.

I agree that 'all around the scene' includes inside corridors and that this presents a discrepancy between the manual and the actual product behavior. I assume that you here implicitly refer to the page Ambient Light which says that ambient light 'is light that is present all around the Scene'. You mention that the current behavior contradicts the manual. The fact that we are discussing this in the first place is perhaps a signal that something is not ideal in the product or in the manual. If we by both 'Ambient Light' and 'Environment Light' refer to the light term controlled by the 'Environment Light' section in the Lighting window, then they are the same. skybox) and reaches a surface via the process of physical light bounces, then they are clearly not the same.

If we by 'Ambient Light' mean light coming from all directions everywhere and we by 'Environment Light' mean light that originates from the infinitely far way environment (e.g. Whether 'Ambient Light' and 'Environment Light' is the same thing or not, depends on what we mean. Does this resolve the particular issue for you? You can clear the lighting by pressing the small arrow next to 'Generate Lighting'.

I suggest you try to make your corridor objects dynamic and/or clearing the baked lighting. Is it static and have you baked a lightmap for it? If so it 'should' be darkened (according to the current intended behavior of Unity which arguably may not be ideal). This may explain why your corridor is dark. objects blocking the surrounding incoming environment light. Instead, they will pick up indirect light from their lightmap.

Static objects with baked lightmaps will not be affected by the single-color environment.

Dynamic objects and static objects without lightmaps have the single-color environment light applied in realtime regardless whether their surroundings are blocked by other geometry or not.

If you disable Skybox in Lighting > Environment and instead choose a single color in Environment Light, Unity currently works like this: To avoid potential confusion/misunderstanding, let me first point out how Unity treats ambient/environment light currently.
