REDsdk 5.3 API Changes

File name	“Change details”
ARTFactory.h	Updated class IDs.
ARTIAssetManager.h	New methods ART::IAssetManager::AddGeometryPart / RemoveGeometryPart: Enhanced geometry control. Entity control API. Modified methods ART::IAssetManager::CreateGeometry: Option to create an atlas or not, skinned mesh option. ART::IAssetManager::BuildGeometryREDGraph: Added sharing capability to the method with pre-existing REDsdk materials. Created images retrieval. ART::IAssetManager::GenerateGeometryVertexAO becomes ART::IAssetManager::GenerateGeometryVertexGI, generating both GI and AO. Related methods modified accordingly. Removed methods Ground field methods. Replaced with decals from the editor.
ARTIAtlas.h	New file with atmospheric control API.
ARTIEntity.h	New methods Animation control API.
ARTIGeometry.h	Modified methods ART::IGeometry::SetVertexAO: Added PBR mesh entry. New methods ART::IGeometry::RefreshMaterial. ART::IGeometry::GetVertexGI and GetVertexAO: Missing accessors. Removed methods ART::IGeometry::SetGroundElevation. Elevation sculpting is now performed using editor decals.
ARTIMaterial.h	New methods New water material parameters API. IOR and glossiness control. Emissive material control methods. PBR material control methods.
ARTIObserver.h	New methods ART::IObserver::GetGPSPosition: GPS conversion query.
ARTIOptions.h	Modified methods ART::IOptions::SetPlanetGeometricalOpsPerFrame becomes ART::IOptions::SetPlanetLandscapeOpsTime. Removed methods ART::IOptions::GetAtlasPrismsDensityRatio and corresponding Set method.
ARTIPlanet.h	Modified method ART::IPlanet::SetEnvironment: Added an environment intensity scaling factor and corresponding accessors. Fixed some API constness mistakes. New methods Wind API: ART::IPlanet::SetWindDirection and other wind control methods. Geometry lazy ground updates control API: API that allow a geometry that has to modify the ground to retain its action until a flush command is issued. ART::IPlanet::GetLandscapeRealHeight: query with optional geometry filtering parameters.
ARTIReflectionProbe.h	New methods ART::IReflectionProbe::SetRenderPlanar / GetRenderPlanar / InitializePlanar: Planar probes control methods. Modified methods ART::IReflectionProbe::SetCameraPosition renamed into ART::IReflectionProbe::SetCameraPositionOffset (same for the Get accessor).
ARTIStatistics.h	New methods Auxiliary rendering time queries (for planar reflections).
ARTIWorld.h	New methods ART::IWorld::SetSimulationElapsedTime: Override of simulation timers. Modified methods ART::IWorld::PickGeometry: Added picked normal to result.
RED.h	New error codes RED_OPEN_IMAGE_DENOISE_DLL_ERROR, RED_OPEN_IMAGE_DENOISE_DLL_NOT_FOUND, RED_OPEN_IMAGE_DENOISE_EXECUTION_ERROR: Intel denoiser specific error codes. RED_SCG_IMAGE_STILL_IN_USE: Multi-threaded image control error code.
REDImageTools.h	New methods RED::ImageTools::GetMeanColor: Get the mean color of a 2D image. RED::ImageTools::CopyFrom: Copy an image from a source. Modified methods RED::ImageTools::ConvertMetallicToRealisticMaterial: Added IOR map support.
REDIGeometryDatabase.h	New method RED::IGeometryDatabase::GetGIDiffuseColor: Get the GI color at a hit object.
REDIMeshShape.h	New methods RED::IMeshShape::GetSkinBonesCount and other bone control / query methods for animated meshes.
REDITransformShape.h	New method RED::ITransformShape::BuildHLRLegacy: Old version REDsdk HLR method for backward compatibility on old scenes.
REDIViewpointRenderList.h	New method RED::IViewpointRenderList::InsertViewpoint: New method with a fixed position insertion.
REDNoise.h	Fixed API constness mistakes.
REDOptionList.h	New option RED::OPTIONS_RAY_ENABLE_OPEN_IMAGE_DENOISE: Turn on or off the Intel denoiser.
REDSoftShaderCallback.h	New parameter RED::SoftFrameBufferSample::_out_bsdf_matte_shadow for the support of path tracing with the matte shadow material.
REDWindowRenderInfo.h	New methods RED::WindowRenderInfo::IsContextSharing: Check how REDsdk will behave about external context sharing (Windows only). Modified methods RED::WindowRenderInfo::SetHostingContext: Added a context sharing option (enabled by default - behavior unchanged).
