Split Render Tool is an add-on designed to help bypass GPU memory limitations by splitting high-resolution images into smaller tiles and merging them automatically. This allows users with lower VRAM graphics cards to render large resolutions that might otherwise cause out-of-memory errors. It works for both single frames and animations.

The tool also provides utilities for isolating specific areas of a render. The Animated Border feature lets you animate the render crop area frame by frame. The Object Border method dynamically sets the crop region based on selected objects, which is useful for re-rendering specific elements of a sequence without rendering the entire frame. It supports all standard image file formats, including OpenEXR Multilayer, and includes options for separating passes into individual files.
