Introduces shadowcaster support by adding shadow map index fields to light data, updating PlayerPositionsToShader and LightdataStorage to handle shadow map indices, and extending the shader and its includes to sample shadowcaster planes. Adds ShadowcasterUpdater script and editor preview for updating world-to-local matrices, and updates relevant arrays and property handling throughout the codebase. Also adds a sample plane mesh for shadowcasting.
Removed the multiply texture and its strength property, and added support for a normal map with adjustable strength. Updated vertex and fragment shaders to handle tangent space and normal mapping, improving surface detail rendering.
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.
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.
Moved light type calculation logic from BlendinShader.shader to a new include file, LightStrength.hlsl, for better modularity and maintainability. Updated the shader to use the new macro for light calculations, improving code clarity and reducing duplication.
