2. Open the “/Assets/Scenes/SampleScene.unity” Scene
3. In Hierarchy, select the “Spot Light“ GameObject
4. In Inspector, try toggling off and on the “Use Shadow Matrix Override“ option and notice how the lighting Scene view changes
5. In the Project window, select “Assets/Settings/PC_RPAsset.asset“
6. In Inspector, change the “GPU Resident Drawer“ to “Instanced Drawing“
7. Repeat steps 3 and 4 while observing the Scene
