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

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

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

Misc

• Migrated cloud ambient LUT to shadesmith tiles for optimized texture management
• Cleaned up SSBO usage
