Alpha Piscium

Highlight

• Reworked ReSTIR GI reuse and denoising to reduce fireflies, specular instability, and temporal artifacts
• Optimized the reuse texture pipeline to lower overhead while keeping clustered spatial reuse effective

New

• Added water wave frequency and speed settings
• Added a PowerShell shadesmith runner for configured local execution

Improvement

• Improved ReSTIR spatial reuse with quad-group / 8-sample grouping, tighter pass limits, and reuse-texture packing changes
• Improved specular GI stability with better temporal reprojection, pairwise MIS metadata handling, and specular-lobe-biased resampling
• Reduced blur and flicker in denoising, TAA, RTWSM, diffuse AO, water surfaces, and auto exposure behavior at low FPS
• Optimized shadow sampling and removed unnecessary work from specular reprojection and caustics filtering
• Updated shader/options/program generation scripts for the current pass layout and multi-properties workflow

Fix

• Fixed ReSTIR spatial reuse texture tiling and continue-trace discard issues
• Fixed specular reprojection failure noise and over-blurred smooth reflections in the denoiser
• Fixed the SETTING_DENOISER_ACCUM switch and the spatial-filter disabling setting
• Fixed TAA edge-pixel out-of-bounds artifacts
• Fixed screen-space shadow acne on very flat surfaces
• Fixed indirect/program pass generation issues

Misc

• Merged GI edge classification with volumetrics depth layers
• Moved ReprojectInfo out of GI common utilities and cleaned up related reuse / temporal code
• Removed obsolete caustics filter, redundant surface-position specular reprojection, and unused GI helper paths
