RenderOne is a Blender add-on that speeds up Eevee rendering with one click. It applies optimized, lightweight render settings instantly and keeps lighting and materials intact while improving speed. It was built around a one-click philosophy, so a set of performance settings can be applied without adjusting each project by hand.
Installation follows the standard Blender route: download the ZIP, open Edit > Preferences, go to the Add-ons tab, click Install and select the file, then enable RenderOne in the list. When updating to a new version, delete the old one and restart Blender before using the latest release.
To run it, press N in the 3D Viewport to open the sidebar, select the RenderOne tab, and click the Apply RenderOne button to switch your Eevee render settings to the optimized setup. The add-on is released under the GPL license and lists compatibility with Blender 5.0 to 5.1. Redistribution of the ZIP file and modification of the source code are not permitted.
