Fast Render Preview earns its place in the superhive library for automating the setting swap that a manual preview render normally requires, handling both the setup and the restore from one shortcut.
Fast Render Preview is a Blender addon from GilaDDD for producing a quick, simple render of your scene. Pressing Alt+F12 triggers a preview, and the addon applies settings suited to a simple image on its own. When the render finishes, it returns the settings to what they were before, so you can move straight back to full-quality work.
Before an addon like this, checking a scene meant manually changing the number of samples, the resolution and more, then reverting all of them afterward — a repetitive step when you want to preview many images. Fast Render Preview handles that setup and teardown from a single button press.
The addon works with the Cycles and Eevee render engines and targets Blender 5.0 to 5.1. It is released under the GPL license and ships with documentation. Version 1.2 updated the addon to fit Blender 5.0 settings, and an earlier release removed the Eevee bloom option after Eevee dropped support for it. A demo video is available.
Fast Render Preview is best for artists who want to check a scene's progress with quick preview renders without manually adjusting samples, resolution and other settings each time.
Fast Render Preview is completely free to download and use.
Fast Render Preview targets Blender 5.0 to 5.1. Version 1.2, released in June 2026, updated the addon to fit Blender 5.0 settings, so it aligns with that release's rendering options. It works alongside the Cycles and Eevee render engines. If you run a different Blender version, check the developer's page to confirm whether it will load correctly, since the listed support only covers these specific releases.
Fast Render Preview works with both the Cycles and Eevee render engines, so you can generate a quick preview whichever one your scene uses. Note that version 1.1 removed the Eevee bloom option, since Eevee no longer supports it. Beyond that, the addon applies settings suited to a simple, small render and then restores your previous settings once the preview finishes. Check the developer's page for more detail.
Fast Render Preview is triggered with a single keyboard shortcut: press Alt+F12 and it produces a quick, small render of your scene. Rather than manually changing the number of samples, the resolution and other settings, the addon applies settings that fit a simple image on its own. Once the render finishes, it returns those settings to what they were before, so your scene is ready for full-quality output again without any cleanup. The addon also ships with documentation if you want more detail.
Fast Render Preview is listed as free in this catalog, and it is released under the GPL license. For current licensing terms, pricing or any changes, check the developer's page, since the terms shown here may differ over time. The addon is developed by GilaDDD and comes with documentation to help you get started, and it supports the Cycles and Eevee render engines. A demo video is also available.
