Updated how light range and spot angle are calculated and packed for both editor and runtime scripts, distinguishing between sphere and non-sphere lights. Adjusted shader logic to use new packing for spot light contribution, improving consistency between CPU and GPU representations.
Replaced usage of GetCosHalfAngle() with spotAngleDeg for spot light calculations in both editor and runtime scripts. Updated shader logic to use smoothstep for light contribution falloff, improving spot light edge smoothness.
Renamed all references, scripts, and editor helpers from PlayerPositionsToShader to LightUpdater for improved clarity and consistency. Updated README and editor preview documentation to reflect the new naming. Added new shader Standard_Lightmap_2SP for enhanced lighting and shadow support.
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.
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.
