v4.14.2

NRD updated to v4.14.2:

• changes due to NRI and MathLib updates

v4.14.1

NRD updated to v4.14.1:

• PT: disabled blue noise in OCCLUSION modes if hitT reconstruction is on (sampling pattern becomes sparse, making blue noise unusable)
• added "improve me" tests for RR

v4.14.0

NRD updated to v4.14.0:

• Upscaling: DLSS and NIS related code removed and replaced with NRIUpscaler extension (also includes FSR/XeSS support)
• Upscaling: added a compile time CNN (legacy) to TNN (fancy transformer) switch for DLSS-SR
• SHARC: switched to SHARC_SEPARATE_EMISSIVE to minimize lags
• PT: improved materialID usage for denoising
• PT: fixed materialID type (no functional changes)
• UI: reflected NRD changes
• CMake: added support for CMAKE_MSVC_RUNTIME_LIBRARY coming from the command line
• reduced code entropy
• updated deps

v4.12.0

NRD updated to v4.12.0:

• integrated DLSS-RR (native integration via NGX API)
• CMake: improvements
• code simplifications to respect NRI v1.163 goodness
• updated dependencies

v4.11.3

NRD updated to v4.11.3:

• PT: hooked up NRD_MaterialFactors
• PT: improved glass
• PT: SHARC usage for specular made lobe-footprint-based instead of "smc"-based
• UI: added "Glass" checkbox, transforming some cubes into glass!
• added NRD_RESTORE_INITIAL_STATE switch
• added CPU-side performance markers
• better stated geometry flags
• NRI updated to v1.158
• updated deps
• updated tests

v4.11.1

NRD updated to v4.11.1:

• PT: added clamping of sampling probabilities for 2nd+ bounces to avoid high energy fireflies
• UI: adjustments
• updated tests
• refactoring

v4.11.0

NRD updated to v4.11.0:

• PT: added 1-bit mask for glass and hair
• PT: fixed dark tails, left by moving emissive objects
• PT: ray offsetting tweaks
• UI: adjustments
• NRI updated to v1.154
• eliminated awkwardness around materialID
• dropped 3D MV
• improved TAA, also fixed potential ghosting and pixelation, while keeping IQ on glass and hair
• added USE_CAMERA_ATTACHED_REFLECTION_TEST

v4.10.0

NRD updated to v4.10.0:

• PT: fixed curvature (scaling from matrices was applied incorrectly)
• PT: curvature computed on the fly, using minimal per-primitive data, coming from the CPU side
• PT: simplified curvature usage for hit distance estimation for NRD (removed some hacks)
• UI: added "boost" option, which is available if SHARC is ON (it's a good practice to shorten history by ~30% if SHARC is available)
• hooked new NRD integration features (FP16 promotion and FP32 demotion)
• NRI updated to v1.152
• code improvements
• updated tests

v4.9.3fixed

Same as v4.9.3 but includes a few simple fixes for some major regressions.

v4.9.3

NRD updated to v4.9.3:

• SHARC: lighting model used for cache population switched to "full" model with "true" specular
• SHARC: improved update to keep cache behind the camera alive
• SHARC: fixed energy conservation for Burley diffuse
• PT: fixed energy conservation for Burley diffuse
• PT: fixed glass behavior on top of a PSR-ed surface (fix after fix)
• PT: lighting at PSR decoupled into direct (shadows go through SIGMA) and indirect (goes through NRD)
• PT: indirect lighting at PSR is split into diffuse and specular according to diffuse probability in case of "1 path perf diffuse, 1 path per specular" mode (had wrong energy)
• PT: eliminated visible seams between L1 (prev frame) and L2 (SHARC) radiance caches
• PT: fixed darkening if prev frame reprojection with confidence < 1 ends the path
• PT: metal and non-metal material IDs get used in PSR like in normal frame
• PT: optimizations
• PT: fixed broken mips for indirect rays (were too conservative)
• fixed potential NANs in curvature
• NRI updated to v1.147
