## Version 1.82

### Added
- LuxURP_BillboardBounds.cs added which lets you tweak the billboards' mesh bounds to prevent them from being culled too early.

Following changes only affect the URP 12.1 package:

### Fixed
- Fixed ambient occlusion debug view for skin, hair, lit extended and clear coat shaders.
- Fixed billboard shader and screen space shadows (upright only, view aligned billboards should not cast shadows at all).
- Fixed DepthOnly shaders.
- Fixed Fuzzy shader declaring _MainTex twice.

### Changed
- Wind, foliage and grass bending reworked:
- - Wind uses simplified inputs.
- - Wind may change the frequencies of higher level animations according to the main strength.
- - Wind derives turbulence from main wind now. Turbulence as set on wind zone will be ignored.
- - Lux Wind params renamed from LWRP to URP. Example: "_LuxLWRPWindDirSize" --> "_LuxURPWindDirSize"
- - Foliage shader now supports additional, advanced turbulence and simple displacement (touch bending - WIP) which has to be enabled in the material inspector.
- - Foliage shader includes vertex color debug mode so no additional shader is required.
- - Grass shader now supports displacement (touch bending) which has to be enabled in the material inspector. The "Lux URP Grass TextureDisplace" shader is deprecated. 
- Shader Graphs: Toon Lighting V1 shaders converted to V2.

### Added
- Tree Creator shaders now support deferred lighting (approximated) and decals.
- Grass Displacement: Shader for trail renderers added.
- Skin shader: Added support for detail normals. 

### Known Issues
