# Alpha Piscium v1.8.5-Beta1

## 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
