Custom Shader Optimizations

Over the past few weeks, development focused heavily on refactoring and optimizing the custom GLSL and GDShader pipelines across Liminalita.

Key Shader Enhancements

• Fragment Pass Performance: Streamlined surface normal map evaluations and screen-space outline calculations, reducing fragment shader instructions and improving framerates in dense room layouts.
• Material & Palette Batching: Combined multi-color outline Passes into single-pass materials to eliminate unnecessary render state changes.
• Water & Transparency Shaders: Optimized the depth and refraction calculations in the aquarium and pool water shaders for consistent cross-platform performance.

These visual and rendering performance improvements pave the way for upcoming environment expansions and level generation features.
