Challenge - Bake the Scene Lighting

1. Use the Profiler to identify an issue with Batching
a. Open the Profiler in Unity, by going to Window > Analysis > Profiler.
b. Play the game and observe the performance profile
c. Use the Rendering Profiler and the GPU Profiler to identify areas for optimization

Figure 01: Profiling the scene before optimization

d. Record the profile data to use as a baseline (never optimize without a baseline)

Figure 02: Saving the Profiler data

1. Configure Static Batching and Light Baking
a. Configure Static and Dynamic batching in Player Settings

Figure 03: Setting up Static and Dynamic Batching in Project Settings > Player

b. Mark stationary objects Static. All of the Module GameObjects can be marked static

Figure 04: Using the Static Checkbox to make an object static

c. Configure the scene lights for Baking.

Figure 05: Switching the Light Mode to Baked, to ensure the light is included in the baking.

Pro Tip: You can use the Light inspector to quickly find and manipulate all of the lights in the scene. ( Window > Rendering > Light Explorer )

d. Use the Lighting Window to bake the scene’s lighting

Figure 07: Baking the scene. Ensure that Baked Global Illumination is checked.

1. Use the Profiler to analyze the results
a. Open the Profiler in Unity, by going to Window > Analysis > Profiler.
b. Play the game and observe the performance profile|
c. Compare to your benchmark
