This is because denoisers can struggle with dark edges of geometry that meet with shadows due to a lack of contrast. (scene 2 Available from the shop.)Ībove 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!Įven 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:Ībove we can see that the bottom of the cupboard area is getting quite badly mangled up by OIDN and even worse with OPTIX. 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. The white background (top of the image) is then added in the compositor to highlight the difference in quality. The image is rendered with film set to transparent to produce an alpha channel. OIDN required over 4 minutes of rendering to achieve a similar quality. Turbo render is able to maintain reflection clarity at extremely low samples. Scene 1 - heavy DOF, strong SSS, film set to transparent to test alpha.
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). To give OIDN and Optix the best possible chance, they were set to use albedo and normals to assist with the denoising process. The following tests were created using cycles X in blender 3.1. Total render time (including denoising) was under 17 seconds on a gtx1070 with an i7-7700k !!!!!!!!
It even works with complex compositing setups without the need to do any rewiring yourself! The results are remarkable as can be seen below.Ĭlassroom scene using the new draft mode. 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. 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). 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.
