_EnableRendering: Toggles the main shader effects (first pass) on or off. When off, the object will be invisible (or transparent), but the Camera Hack overlay (second pass) may still function if enabled.
Texture
_MainTex: The main input texture that the effects will be applied to.
Resolution Width / Height
_FixedResolutionWidth, _FixedResolutionHeight: Sets the target low resolution. The input texture is effectively downscaled to these dimensions, creating the pixelated look.
Is Fullscreen Effect
_IsFullscreenEffect: (Informational) Indicates if the shader is intended for use as a fullscreen camera effect (like a post-processing effect).
Object Aspect Ratio
_ObjectAspectRatio: Adjusts the aspect ratio for non-square objects (like quads) when *not* using the fullscreen effect, helping to prevent stretching.
Enable Color Depth Reduction
_ColorDepthEnabled: Turns the color reduction effect on or off.
Color Depth
_ColorDepth: Reduces the number of available colors, simulating retro hardware limitations. Lower values mean fewer colors (more posterized look).
Contrast
_Contrast: Adjusts the difference between light and dark areas.
Brightness
_Brightness: Adjusts the overall lightness or darkness of the image.
