untitled Shader menu

a sleek, draggable shader menu with two main tabs: Main (Custom Settings): Contains sliders to allow the user to tweak individual post-processing properties in the Lighting service, such as Brightness, Contrast, Saturation, Bloom, and Sun Rays. Changes are applied in real-time (ApplyCustom). Shaders (Presets): Offers a list of pre-configured shader modes (e.g., Glossy, Vintage, Neon). Only one preset can be active at a time, which applies a complex set of lighting effects (ActiveShader logic).
