Why we like it

Earns its place in the superhive library as a small, single-purpose utility: it automates one specific habit, pausing the viewport render during an F12 render, so you don't have to remember to do it manually. The native Cycles integration and persistent settings keep it out of the way once enabled.

What is Auto-Pause Viewport?

Auto-Pause Viewport is a Blender add-on that manages what your viewport does while a final render is running. When you press F12 to start a Cycles render, it pauses the viewport render, then automatically resumes it once the final render completes or is canceled. This keeps the viewport from eating up GPU resources during a render that needs them.

By reducing GPU load in this way, the add-on frees performance for Cycles renders. It works natively with Blender's Cycles render engine, and you can enable or disable the feature directly from the viewport shading menu. Your preferences stay saved between sessions, so the setting carries over each time you reopen Blender.

Setup is straightforward: install, enable, and let it run, with no complex settings to configure. Auto-Pause Viewport is compatible with Blender 3.0 and above, covering versions 3.0 through 4.5, and it ships under a Creative Commons license. A demo video is available for a closer look.

Who is Auto-Pause Viewport best for?

Auto-Pause Viewport is best for cycles users in Blender who run long F12 renders and want to keep the viewport from drawing on GPU resources during them, including freelancers, studio artists, and hobbyists.

How much does Auto-Pause Viewport cost?

Auto-Pause Viewport is completely free to download and use.

Frequently asked questions

Does Auto-Pause Viewport work with Blender 4.5?

Auto-Pause Viewport is compatible with Blender 3.0 and above, with listed support spanning versions 3.0 through 4.5. If you're running a release in that range, the add-on works as described, pausing your viewport render on an F12 final render and resuming it afterward. For versions newer than 4.5 or older than 3.0, compatibility isn't stated, so check the developer's page for current details before installing on a build outside the listed range.

Does Auto-Pause Viewport work with Eevee or only Cycles?

Auto-Pause Viewport works natively with Blender's Cycles render engine. Its pause and resume behavior is built around Cycles final renders triggered with F12, so that's where the add-on applies. Support for other engines such as Eevee isn't stated, so if your project renders outside Cycles, confirm the details on the developer's page first. For Cycles users, the add-on integrates with the engine directly and needs no complex configuration beyond installing and enabling it.

How do I turn Auto-Pause Viewport on or off?

Auto-Pause Viewport can be enabled or disabled directly from the viewport shading menu, so toggling the feature doesn't require digging through separate preference panels. Your choice is remembered too, since the add-on keeps its settings persistent between sessions. That means you set it once and it carries over the next time you open Blender. Beyond the toggle, the workflow is simply install, enable, and let it run, with no complex settings to manage.

Is Auto-Pause Viewport free, and how is it licensed?

Auto-Pause Viewport is listed as free in this catalog. Licensing and any current pricing can change, so the developer's page is the best place to confirm the latest terms before you download. The add-on is distributed under a Creative Commons license. Once you have it installed and enabled, it runs quietly, pausing your viewport render during F12 renders and restoring it when the final render completes or is canceled.
