Render Controls - Postprocessing

The Postprocessing tab contains controls for postprocessing of the render.

Figure 1: The Postprocessing tab

• Exposure: Changes the linear exposure of the image.

• Postprocessing filter: Dropdown menu to select the postprocessing filter (tone mapping) applied to the render. Chunky includes the following postprocessing filters.

  • None: Disables use of any postprocessing filters on the render.

  • ACES filmic tone mapping: Uses the ACES filmic tone mapping curve approximation by Krzysztof Narkowicz.

  • Gamma correction: Perfoms gamma correction only (the most basic tone mapping).

  • Hable tone mapping: Uses John Hable's Uncharted 2 tonemapping function. This postprocessing filter is currently missing gamma correction; this will be fixed in a later release. The current implementation of the postprocessing filter may be moved to a plugin later.

  • Tonemap operator 1: Uses the tone mapping formula by Jim Hejl and Richard Burgess-Dawson.

Other postprocessing filters can be added through the use of plugins, such as the Bloom plugin, which adds a postprocessing filter for bloom effects.

The best postprocessing filter to use depends on the scene and the look which you are attempting to achieve.
