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.
Introduces a _BlurPixels property and related parameters to BlendinShader and LitParticles shaders, enabling blurred shadowcaster sampling. Updates Shadowcaster.cginc to support blurred texture sampling using tex2Dgrad when blur is enabled. Also adjusts light intensity calculation in LightStrength.hlsl to remove NdotL multiplication for consistency with new shadow handling.
Replaces the use of world-to-local matrices for shadowcaster planes with explicit plane origin, basis, and normal vectors in both C# and shader code. Updates property setting in ShadowcasterUpdater and its editor preview, and rewrites the shadow sampling function in the shader include to use the new basis. Adjusts all affected shaders to use the new properties and sampling function for improved clarity and flexibility.
Extended ShadowcasterUpdater and shaders to handle multiple shadowcaster planes by introducing indexed properties and logic for two shadowcaster sets. Updated property names and shader logic to support per-index shadowcaster textures, colors, and brightness, enabling more flexible shadow casting in scenes.
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.
Introduced shadow caster texture, color, outside color, and minimum brightness parameters to the LitParticles shader. Moved related variable declarations to Variables.hlsl for reuse and removed redundant declarations from BlendinShader.shader. Updated LitParticles lighting calculation to apply shadow caster effects when appropriate.
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.
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.
Changed shader property names to use '_Udon_' prefix and switched to using VRCShader.PropertyToID and VRCShader.SetGlobal* methods for setting shader properties. Added update throttling in LateUpdate for performance. These changes improve compatibility and efficiency with the VRC SDK3 Rendering API.
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.
