MP_Comp is a comprehensive collection of over 100 custom node groups designed for Blender's native compositor. The library provides artist-friendly controls for real-time post-processing and visual effects directly within the viewport. It includes tools for color correction, distortion, generative elements, and stylistic filters like VHS or comic overlays. The presets are optimized for speed and can be accessed via the asset browser, making them suitable for both single renders and video sequence editing.
