Property	Information
`Render Pass Event`	Leave at `Before Rendering Post Processing` for best results.
`Layer Mask`	Which layers to include when rendering the effect.
`Shader`	The anaglpyh shader, located at the root directory of the package.
`Spacing`	The spacing between the red and cyan channels. A value of `0` will ignore the focal point. This is useful for orthographic cameras. A negative value will swap the red and cyan.
`Focal Point`	The point `x` units in front of the camera where the red and cyan channels meet.
`Overlay Mode`	`None` - Replace the background with the effect. This is ideal for rendering the entire screen with the effect. `Opacity` - Overlay the effect based on its opacity. `Depth` - Overlay the effect based on its depth.
`Blend Mode`	`None` - Do not blend the effect onto the background. `Additive` - Perform stylistic blending by adding the effect to the background. `Channel` - Perform correct blending based on each eye's channels.
`Opacity Overlay Render Texture Format`	The render texture format to use when `Overlay Mode` is set to `Opacity`.
`Depth Overlay Buffer Bit Count`	The depth buffer bit count to use when `Overlay Mode` is set to `Depth`.

Rendering with this effect may be expensive, since the whole screen must be rendered multiple times every frame.
Overlay Mode > Opacity requires a transparent render texture format, which can be set with Opacity Overlay Render Texture Format.
Overlay Mode > Depth does not work with transparent objects, such as text with TextMesh Pro.
