GI visualization in the Unity 12.1 scene View

When designing different scene content in the scene view, you can tick the relevant rendering options as needed to let the scene display only one or all of the rendered effects.

In these modes, a set of patterns can see what the global illumination is doing. By default, the texture mode illuminates the scene completely based on the GI settings.

Other GI-related patterns include: albedo (Albedo), Emission Light (emissive), UV chart (UV Charts), irradiance (irradiance), directionality (directionality), System (systems), Baking (Baked). This section mainly introduces these basic concepts. Second, the Parameter setting window (Lighting windows)

In Unity 5, the Lighting window is the global Illumination (GI) master, which, by default, automatically handles light maps and lighting effects, and can further adjust the relevant parameters through the window.

You can set the relevant parameters by using "window", "Lighting" in the menu bar to open the Lighting window.

Demonstrates how to open lighting window and the options that are rendered in the Lighting window view:

Attention:

(1) The Object tab in the lighting window displays the texture of the selected object and the UV channel that is rendered on the object. That is, you must first select an object in the scene before you can see the related properties.

(2) The "Auto" is checked by default at the bottom of the lighting view, which means that unity is automatically baked in the background immediately by the parameters set, and the benefit is that the baking effect can be seen as soon as possible (baking takes time, so it is not immediately possible to see the baking effect).

(3) If you want to manually change the details of the baking parameters and let unity bake according to the parameter details you set, you need to uncheck "Auto", and then click "Build" to bake after you have finished modifying all the parameters. Third, the scene view can choose to render the visual layer

In the scene view of Unity 5, you can select only one or more visual layers you want to see, in addition to the default rendering of all layers. Includes: Albedo (Albedo), Emission Light (emissive), UV chart (UV Charts), irradiance (irradiance), directionality (directionality), System (systems), baking (Baked).

1. UV chart (UV Charts)

The UV chart shows the optimized UV layout layer, which is used to calculate dynamic GI, which is a layer that is automatically generated during the pre-calculation process. This layer becomes available only if you have completed the precomputed phase of the instance.

2, System (systems)

In the preprocessing phase (Precompute stage), Unity automatically divides the scene into a single systems, so that a group of objects can share or approximate share the same lighting mapping settings. This is mainly to be in the background through multi-threaded automatic optimization preprocessing process, after processing the system will automatically use a different color to visualize the effect.

3. Albedo (Albedo)

Displays the albedo used to calculate the dynamic GI.

4. Emitting light (emissive)

Displays the light emitted by the object used to calculate the dynamic GI.

5, irradiance (irradiance)

Displays the effect of indirect illumination (indirect light), that is, the contents of a dynamic light map.

6. directionality (directionality)

Displays direction information for the matching irradiance (irradiance).

7. Baking (Baked)

Displays the light map effect after baking.

After understanding these basic concepts, we can continue to learn the parameters of the setting.
