Split is a Blender add-on that introduces a dynamic split-screen comparison tool to the 3D Viewport. It allows artists to instantly compare a stored compositing state against the current active state using a draggable split line. Designed to replicate the store render buffer functionality found in other 3D software, it leverages the real-time compositor for immediate visual feedback. Users can customize the comparison line's thickness and color directly from the sidebar panel. The tool is compatible with EEVEE, Cycles, and Octane render engines.
