Alpha Piscium

Highlight

• Major improvements to ReSTIR SSGI stability and quality

New

• Readded RCRS anti firefly to GI denoiser pipeline
• Added ReSTIR Temporal Reuse Limit setting for better user control on GI responsiveness
• Added FXAA as TAA history missing fallback

Improvement

• Combined sun and moon Sky-View LUT
• Optimized colored shadow precondition check
• Uses blue noises in ReSTIR for better noise distribution
• Reduced denoiser history fix leaks
• Improved shadow AABB calculation and cleanup
• ReSTIR uses full bilateral bilinear temporal resampling to improve stability and quality
• Updated default accumulation settings for less lighting lags
• Reduced GI reprojection false anti-stretching history kills
• GI denoiser history fix skips first 3 LODs for fewer fireflies
• Replaced bloom hard clipping with soft clipping
• Switch TAA variance AABB history ratification from clamping to clipping
• Optimized ReSTIR reuse passes
• Water volume tweak
• Use AABB clipping for fast history clamping
• Use bilinear on fast history for free blurring and fewer noises
• Use distance between probe pixel position and origin position as fade distance

Fix

• Fixed atmosphere mie coefficient calculation for low turbidity value
• Fixed DH water material detection
• Fixed DH water shadow blending
• Fixed random emissive from DH solid
• Slightly mitigated shadow acne
• Fixed SSS singularity bug in SRGB rendering working space
• Removed denoiser stabilization pass to fix bleeding
• Fixed GI grid pattern artifacts caused by bad reprojectInfo.curr2PrevScreenPos precision
• Fixed TAA reset missing
• Fixed emissive bug on 0 albedo material

Misc

• Migrated cloud ambient LUT to shadesmith tiles for optimized texture management
• Cleaned up SSBO usage
• Removed env probe setup clearing
• Fixed make zip naming
