Major Feature Release – Turbo Tools V3 now with Temporal Stabilizer and the option to use animation optimised sample pre-sets!
Turbo Tools is a full rendering pipeline addon that includes:
Turbo Render – Vastly superior render results up to 960x faster. Retains image quality the standard denoisers can’t maintain even when providing them with images rendered for 120X longer! For complex scenes you can expect your single frame renders to be reduced from several hours to several minutes!
Temporal Stabilizer – Although only a single checkbox, this massive new feature provides per pass temporal stabilization, allowing animation render times to be reduced by up to 40x! Check out the YouTube introduction video to find out more:
Turbo Comp – A full compositor suite with real-time playback and compositing directly in the compositor backdrop, branch caching, resaving of file output nodes without re-rendering, automatic file output node creation, publishing and lots more.
In difficult to render scenes (indoor scenes, volumes, scenes containing glossy materials with detailed textures, SSS, etc) Turbo Render provides results that OIDN/Optix could require you to render up to 120x longer in order to match Turbo Render’s results. When no denoiser is used you could expect to render up to 960x longer to achieve the same results produced by Turbo Render (scene dependant). Additionally it simplifies the entire rendering process thanks to render setting pre-sets designed to help you get the result you need without diving into the complex render settings. It even works with complex compositing setups without the need to do any rewiring yourself! The results are remarkable as can be seen below.
Classroom scene using the new draft mode. Total render time (including denoising) was under 17 seconds on a gtx1070 with an i7-7700k !!!!!!!!
The following tests were created using cycles X in blender 3.1. To give OIDN and Optix the best possible chance, they were set to use albedo and normals to assist with the denoising process. OIDN had Prefilter set to Accurate, and I also tried setting prefilter to NONE to see if it would improve the texture comparison results (it didn’t).
Scene 1 – heavy DOF , strong SSS, film set to transparent to test alpha.

Test scene 2 Available from the shop.
Turbo render is able to maintain reflection clarity at extremely low samples. OIDN required over 4 minutes of rendering to achieve a similar quality.
The image is rendered with film set to transparent to produce an alpha channel. The white background (top of the image) is then added in the compositor to highlight the difference in quality. OIDN required a 4 min render to get close to Turbo Render’s 10 second render result, but there was still visible noise (video to follow)
Scene 2 – Indoor scene to test geometry detail and texture detail.
Above we can see that even after 30 minutes of rendering, OIDN is still unable to retain as much texture detail as Turbo Render can at on 1 min!
Even with a 15 second render, that’s a whopping 120x faster than the 30 min render used by OIDN, Turbo Render can still maintain texture detail using it’s ‘Enhanced Textures’ option:
Above we can see that the bottom of the cupboard area is getting quite badly mangled up by OIDN and even worse with OPTIX. This is because denoisers can struggle with dark edges of geometry that meet with shadows due to a lack of contrast. Turbo Render can achieve much better results using it’s ‘slow (all passes mode), even at very low samples (as shown above bottom right).
Below shows that even when rendering at 1 min per frame (240x less time per frame than the ground truth 4 hours per frame), we can still get excellent results without any noticeable flicker. To do this with OIDN and maintain the same geometry, texture and reflection detail we’d need to render at 30 mins per frame (as can be seen in the above texture comparison still image examples, and youtube video examples athttps://www.youtube.com/watch?v=toManFMUSFQ ).
Notice how turbo render (on the right) has vastly superior image quality when compared to OIDN (left). The most noticeable improvements in this image are the crisp shadows on the notice board and the clarity of the reflections under the desk.
The UI is very simple to understand, and offers options to ensure the best possible results for any scene and sample settings.
Turbo Render is designed with ease of use being a top priority. In the Turbo Render Options area, simply click enable, choose a sample preset to automatically set up the sample settings to the desired quality, choose the cleaning mode (combined image or clean passes), tell it what’s in the scene, and render. That’s it! Turbo render will then analyse the scene and other render settings to produce the final render. IMPORTANT ensure a default project cache folder for new scenes is specified in the addon preferences, and that each scene has a valid cache folder set prior to rendering. The scene’s cache folder can be set at the bottom of the Turbo Render options, or in the compositor’s N panel turbo tab. If you the ‘User’ sample pre-set, then to achieve the biggest speed gains, you should reduce your samples below what you would usually need. Turbo Render is so fast because it’s able to produce clean images from noisier render results than other denoisers can.
Turbo Render is compatible with:
Existing compositor trees
Rendering of multiple scenes and view layers from a single compositor (all scenes will use their own Turbo render settings).
All Turbo Comp features (caching, publishing, resaving file output nodes without re-rendering etc)
