Introduced an _EnableShadowCasting property to BlendinShader, LitParticles, and Water shaders, allowing shadow casting to be enabled or disabled via a material parameter. Updated shadow sampling logic to respect this toggle, and added related parameters and includes where necessary. Also added a Cull Mode property to BlendinShader for improved rendering control.
Added tangent and bitangent calculations to the vertex shader and used a TBN (tangent, bitangent, normal) basis to properly combine and transform normal maps in the fragment shader. This enhances the realism of water surface lighting by accurately handling multiple normal maps.
Updated all relevant shader files and C# script to use Udon-prefixed light and player variables (e.g., _Udon_LightPositions, _Udon_LightColors, _Udon_PlayerCount) for consistency and to avoid naming conflicts. This change affects variable declarations, macro definitions, and all usages in BlendinShader, LitParticles, Water shaders, and included HLSL files.
Introduced a new WaterParticle shader for rendering water particles with alpha blending. Made minor formatting and calculation adjustments in Water.shader and DefaultSetup.hlsl, and updated Variables.hlsl. Added corresponding .meta files for new shader assets.
Replaces direct variable declarations and code blocks related to 'MoonsLight' with a new 'MoonlightGlobalVariables' macro included from Variables.hlsl. Adds OutLoopSetup macro for loop setup, updates all relevant shaders to use the new macros, and renames comments and identifiers from 'MoonsLight' to 'Moonlight' for consistency. Removes the obsolete MoonsLight.cingc include and its meta file.
Modularized lighting calculations by introducing DefaultSetup.hlsl and Lambert.hlsl includes, and updated BlendinShader, LitParticles, and Water shaders to use these macros. Added new wave-related properties and logic to Water.shader for enhanced wave effects. Improved maintainability and consistency across shaders by centralizing light and Lambertian diffuse calculations.
