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.

Notes

• 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.
