Why we like it

RenderBoost earns its place in the superhive library by targeting a specific bottleneck, long animated render times, through frame interpolation instead of rendering every frame directly. The base addon covers interpolation and automatic video output, while a Pro version layers on GPU acceleration, denoising, and upscaling. Results vary by scene and hardware, so it suits iterative work where quick turnaround matters.

What is Renderboost Addon?

The RenderBoost Addon speeds up animated renders in Blender using frame interpolation. Instead of rendering every frame, it generates additional frames from your existing image sequence, so fewer frames need to be rendered directly. The developer states this can cut animated render times by up to 80%, though the actual savings depend on your hardware; testing was carried out on a system with an NVIDIA GeForce RTX 3070 Ti, AMD Ryzen 7 3700X, and 32GB of DDR4 memory.

The interpolated frames blend with your rendered frames to keep motion fluid, and customisable settings let you set the number of interpolated frames to balance smoothness against computational cost. The addon also handles automatic video creation, offers command line support, and integrates into your existing Blender workflow with its own interface and controls.

A separate RenderBoost Pro version adds GPU acceleration to speed up interpolation, plus advanced denoising and upscaling. Because the tool relies on interpolation, scenes with fast-moving objects or heavy motion blur can occasionally produce artifacts, and the addon is actively developed with ongoing bug fixes and new features.

Who is Renderboost Addon best for?

Renderboost Addon is best for meeting tight deadlines and speeding up the iteration process on animated Blender projects.

Frequently asked questions

Which Blender versions does the RenderBoost Addon support?

RenderBoost Addon supports Blender 4.2, which was added in version 0.2.3, and Blender 4.1, added in version 0.1.4. The addon integrates into your existing Blender workflow with its own interface and controls, and it is actively developed with recent updates including background improvements and bug fixes. Installation has seen fixes for macOS and adjustments to how dependencies are handled, with instructions provided for installing those dependencies. For the exact list of supported versions and current requirements, check the developer's page and the included documentation before installing.

What is the difference between RenderBoost and RenderBoost Pro?

RenderBoost comes in a base version and a Pro version. The base version handles frame interpolation and automatic video creation. RenderBoost Pro adds GPU acceleration to speed up interpolation times, along with advanced denoising and upscaling. According to the developer, you can start with the base version and upgrade to Pro later if you decide you need those extra capabilities. A Pro video series is also mentioned on the developer's page for a closer look at what the upgrade offers.

Does the RenderBoost Addon produce artifacts on fast motion?

RenderBoost relies on frame interpolation, which generates extra frames from your existing image sequence, so results can vary from scene to scene. The developer notes that scenes with multiple objects moving at high speed, along with heavy motion blur, can sometimes produce artifacts, which is a known limitation of the interpolation approach. The developer aims to keep improving the addon with future features to mitigate these edge cases across different scenes and use cases, and welcomes bug reports and feature suggestions.

Does the RenderBoost Addon support command line use?

RenderBoost Addon supports command line use, which was added in version 0.1.1, and the developer points to the included Readme file for example usage. This sits alongside the addon's standard interface inside Blender, giving you another way to run the tool. The version history also shows additional tools such as a shots tool added in version 0.0.9 and GPU acceleration introduced in version 0.0.6. Check the documentation for setup details and current usage instructions before you get started.

Is the RenderBoost Addon free?

RenderBoost Addon is listed as free in this catalog. There is also a Pro version that adds GPU acceleration, advanced denoising, and upscaling, and the developer notes you can upgrade from the base version later. Because licensing and any paid tiers can change over time, check the developer's page for the current terms before you rely on any particular option. That way you will know exactly what the free version includes and what the Pro upgrade adds.
