Overview of changes

The main feature available with REDsdk 5.3 is the integration of the Intel Open Image Denoiser, using extra libraries from Intel that can be loaded up. See the Denoising with Intel Open Image Denoise to jump into the details. Using the Intel Denoiser is performed as a post-processing step, unlike REDsdk's denoiser.

Among other changes: REDsdk's Metal support has been slightly enhanced, fixing a number of back-end hardware issues. AMD support had to be modified a lot after a few Adrenalin driver issues atfer version 21.4.

REDart has been evolved a lot and continue to be improved both in quality and performance. We can list:

• Enhanced geometry operations: for adding parts, removing parts, changing materials inside a geometry part. These operations are now faster and avoid the reconstruction of the entire geometry when performed, resulting in a greater interactivity when operating with REDart.
• Geometry texture atlas sharing: This is a new feature in geometries: identical atlases for different geometries are catched-up and shared automatically.
• Atmospheric control API: A new ART::IAtlas interface adds atmospheric controls.
• Enhanced vertex GI / AO quality: The overall quality of a vertex based GI / AO has been enhanced providing a better look & feel.
• Enhanced performance: Worked a bit on display performance in complex natural environments.
• Export Decals from the editor to define fields in landscape environments: Now decal documents from the editor can be exported into scene atlases. These can be used to define fields or sculpt the terrain.
• PBR native materials: The support for native PBR sources has been added to the ART::IMaterial.
• Water surfaces and water rendering materials (using editor decals): Water rendering was added and several types of water surfaces can be defined.
• Planar reflection probes: A new type of probes based on pure planar reflections has been added. Very handy for interior rendering of grounds. Not free in terms of performances but worth it.
