2D Renderer Data Asset
The 2D Renderer Data Asset contains the settings that affect the way Light is applied to lit Sprites. You can set the way Lights emulate HDR lighting with the HDR Emulation Scale, or customize your own Light Blend Styles.
Use Depth/Stencil Buffer
This option is enabled by default. Clear this option to disable the Depth/Stencil Buffer. Doing so might improve your project’s performance, especially on mobile platforms. You should clear this option if you are not using any features that require the Depth/Stencil Buffer (such as Sprite Mask).
Post-processing Data
Unity automatically assigns a default Asset to this property that contains the resources (such as Textures and Shaders) that the post-processing effects require. If you want to use your own post-processing Shaders or lookup Textures, replace the default Asset.
