Advanced Render settings

The Vignette Authoring Tool (part of the Scene7 Image Authoring package) provides mechanisms to control low-level aspects of the vignette render engine.

NOTE

Render Settings is an advanced feature of Image Rendering and Image Authoring. Contact Adobe Technical Support or your Adobe consulting representative for training, consultation, or both, on using Render Settings.

These settings are controlled interactively in Image Authoring. It is possible to apply the same settings in Image Rendering using the rs= command (or with the catalog::RenderSettings value). This mechanism is used to select different sharpening options for each material, and modify the behavior of the illumination rendering algorithms, such as varying the saturation of highlights or the contrast in shadows.
