# Alpha Piscium v1.8.5

## 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
