OCP "1-Click Proxy" is a Blender add-on for automating proxy creation. With one click, it replaces high-poly objects with lightweight proxies, boosting viewport performance while your original models and materials stay intact. The Auto Scan + Face Count Logic finds the highest-poly objects and swaps them for clean proxy objects using thresholds you can customize.
You choose how proxies are generated: category presets that auto-load, Bounding Box, Convex Hull, or a custom proxy you apply to every object at once. Smart Material Transfer carries your materials across, keeping the test-render look even on Convex Hulls or custom geometry. Global controls apply or remove proxies across all selected objects, and you can toggle between high-res and proxy views. A Batch Decimation Panel reduces geometry across multiple objects with visual feedback and thresholds.
Proxies never appear in final renders, so output always uses your original models. The add-on lives in the 3D View N-panel with buttons for adding, deleting, and customizing proxies, live feedback, and an auto-save option that applies proxies before Blender closes. It runs on Windows, macOS, and Linux, and ships with a demo video, screenshots, and documentation.
