AgMax is a compositor node group that serves as an alternative to Blender's built-in view transforms like Filmic, AgX, and Khronos PBR Neutral. It provides manual control over highlight rolloff curves and dynamic range compression, allowing users to adapt the tonemapping for both high-contrast outdoor scenes and evenly lit portraits. The tool includes adjustable Abney Effect compensation to prevent saturated bright colors from shifting hue, ensuring that intense reds and blues render accurately without turning pink or purple.
