Learn to make cutscenes in unity3d by building a stealth Game.
Objective: Understand What is Ligh Probes.
What are Light Probes?
Light Probes provide a way to capture and use information about light that is passing through the empty space in your scene.
So How is this helpful?
Light probes are used to provide high-quality lighting(including indirect or bounced light) on moving objects.
A Light Probe is a performance savior before this using high texture for self-luminous with many light sources used to cost a lot and can cause performance issuer for low-end devices like mobile devices and low pc.
The secondary use of light probes is to provide the lighting information for static scenery when that scenery is using Unity’s LOD system.
In order to see how our dynamic object clear is affected by light, delete the direct light, in order to see how the dynamic object is affected by the light probe group, then disable the light used to light the scene.
Note: I have deleted the direct light and disabled the scene light to make sure you see clearly the effect of the moving object, so it's not a step.
Note: In order for this to work the self-luminous object must be static since we use baked light.
Now go to create < Ligh < Light Probes Group, this will create objects with dots that are light probes.
In the next step, select the light probe group < Inspector and then click edit then duplicate some points by selecting and hitting ctrl + d then move different dot of the light probe to a different place of the security desk, we do this in order to make sure the light probe catches the light from a different angle of the desk, so it can share the light with the dynamic object.
Note: Make sure when placing the light probe do not drag these dots inside the object or inside the floor you will experience a weird behavior
Now let's move the circle which is a dynamic object, you will notice the circle is lighting up using a light probe according to the point of the light probe it is.
As you see our dynamic object is picking light according to some point of light the probe which has been placed in a random place near our desk. See you in the next article.
