What is real time lighting?

Real-time Lights are Light components which have their Mode property set to Realtime.

For example, you can set them to switch on and off (like a flickering light), change their Transforms (like a torch being carried through a dark room), or change their visual properties, like their color and intensity..

What is the difference between global illumination and local illumination?

Local illumination – idea that objects are only illuminated directly by the light sources. Global illumination – idea that objects do not only reflect light to the viewer, but also to other objects.

How do you use area lights in unity?

Area lights are like if a rectangle projected light in one direction. This can be used for more realistic interior or street lighting, and in the same ways point lights might be used. Add an area light by going to GameObject > Light > Area Light .

How do you bake light area?

How Do I bake Area LightsMake sure the objects are static for lightmapping.Make sure the area lights point to right direction.Make sure the range of the area light reaches the objects.For fast testing you could use less light, smaller resolution, lower quality and so on to make the lightmap baking faster.

What is a point light?

The Point Light emits light equally in all directions, similar to a light bulb or a candle flame as all rays originate from a single point. Point lights obey the physical law of inverse square falloff for intensity.

What is global illumination in unity?

Global Illumination (GI) is a system that models how light is bounced off of surfaces onto other surfaces (indirect light) rather than being limited to just the light that hits a surface directly from a light source (direct light). … Global illumination in the Scene View.

What is bake unity?

With dual lighmaps, Unity bakes both lightmaps with shadows and without. It then uses the shadow distance to determine where to fade between lighmap shadows and realtime shadows.
