## Highlight
- **Added limited Built-in PBR support**
- **Improved translucent rendering with double refraction**

## New
- Added limited Built-in PBR support (Foliage SSS, Translucent, and Emissive)
- Added double refraction for non-water translucents for more accurate light bending
- Added more per-material translucent absorption settings

## Improvement
- Migrated TranslucentSST to the new SST implementation, greatly simplifying the code
- Improved cloud spherical shell setup
- Improved water scattering with new phase function based on Petzold data

## Fix
- Fixed translucent sky reflection error
- Fixed DH (Distant Horizons) support
- Fixed missing TAA clamp mix logic
- Fixed cloud spherical shell setup
- Fixed insanely bright emissive from end rod and charged lightning rod

## Misc
- Increased default PCSS sample count for better shadow softness
