Post‐Processing Stack

Post-processing stack implements several image effects as a single full-screen draw.

Setup

• In the project window, right click and select Create/Toon RP/Post-Processing/Post-Processing Stack.
• Go to your pipeline asset, make sure the post-processing is enabled, and add the newly created stack to the Post-Processing Passes list.

Effect List

• FXAA
• Tone Mapping
• Vignette
• LUT
• Film Grain

Tone Mapping

Maps HDR colors into a more visually suitable range.

Uses an exponential function:

$$ X_{out}=1-e^{-X_{in} \times exposure} $$

Vignette

Darkens corners of a picture.

LUT

LUTs (Lookup Tables) apply applying a predefined filter to an image. By default, it uses the Default LUT (neutral) filter, which can be used as a reference for the layout, format, and filtering modes required for LUTs.

Film Grain

Applies a noise pattern to a picture. Toon RP comes with two built-in noise textures: FilmGrain and FilmGran_LowSaturation.

The effect only applies to dark parts of the image, the threshold can be controlled via the Luminance Threshold parameter.
