Render faster and spare a lot of money. E-Cycles is a fork of Cycles which renders up to 2.7x faster out of the box when using CUDA GPUs, more using new options. You can get weekly E-Cycles builds based on Blender 2.79x and 2.8x, with support for Windows, Mac and Linux.
You can buy E-Cycles now on Gumroad based on Blender 2.8x or 2.7x to get all the features that will come in 2019. Their is also a monthly option for 2.8x. You can also get E-Cycles on the Blender Market .
An optimised RTX Version is also available: 50% off during beta https://gumroad.com/l/ECyclesRTX/beta. See users results.
Note: E-Cycles 2019 patches will progressively become public in 2020, so everybody can benefit from it for free. If you want new speed improvements, regularly updated builds, support and tutorials and you want me to continue to work on improving Cycles/E-Cycles, you can pre-order one of my 2020 products: E-cycles AI denoiser, standard/GTX or RTX 2020 version on Gumroad and the Blender Market. If funding for E-Cycles 2020 reaches the same level as the one the BF takes per developer and year, I’ll even be able to work like them with everything public on day one and I will.
The speedup of about 2x is reached out of the box (open the file, hit render) thanks to:
- better memory access
- better parallelism so that all CUDA cores are better occupied
You can get more speedup thanks to the following new/enhanced options:
- An enhanced path simplification (up to 3x faster)
- A new AI denoiser which works at very low sample (interiors can be rendered for animation with less than 200 samples, compared to over 1000 usually, original library from Intel and patch by @skw )
- an option to only do the pre-processing step once per video for flythrough (where only the camera moves, only available in 2.79x based version, based on a patch from Lukas Stockner)
You can have a look to the following video for a result of using most of the above mentioned techniques to get about 14x faster render (5 minutes to 22 seconds on a single 1080Ti). A short tutorial showing how the scene was setup is included in all E-Cycles versions.
Scene from Evermotion
With E-Cycles, you can:
- render 1.6x up to 2.7x faster out of the box with CUDA and regular path tracing, using the same settings or render much more realistic images in the same time as the normal release (see table in the FAQ for more details).
- get fast support and bug fixing
- render cleaner images at the same sample count (all versions) or have the same noise as official Blender (2.79x only, about 30% slower, allow to mix frames rendered with official versions and E-Cycles)
- spare time by using auto tile size
- buy a much cheaper and more quiet GPU yet having the same performance as the big one
- the improvements will be submitted to the Blender Foundation after a year
- February update: 5% faster and with the new Intel denoiser. This render took 7sec at 100% (4 times the resolution of the original BMW benchmark file) on a single 1080Ti:
- March update faster viewport in typical interiors using path tracing with CUDA. Here is a comparison after 2sec of rendering in the viewport with master (noisy, 64spp) and E-Cycles (much cleaner, 7spp):
And E-Cycles live viewport rendering in Evermotion’s scene 009:
The render times compared between latest buildbots and latest E-Cycles:
pure path tracing time (pre-procesisng time will depend on your CPU)
If you took part to my course, you can get any version at 50% off, just ask per PM.
If you provide a proof that you are student (university or college), PM me, you can get E-Cycles 2.8x for 25€ for all 2019 updates or 5€/month.
Professionals can get the 2.7x build:
- it has an option to get the exact same output as master, with still up to 1.7x faster rendering compared to master.
- it is build on the stable 2.79.x version
- the 2.8x builds are also available as a bonus to slowly switch to it
- Denoising with the new Intel denoiser is much faster
- the preprocessing phase is only done once in fly-through videos (were only the camera moves), allowing to render such videos in some seconds per frame:

You can also learn how I did it with a course to create your own Blender version.
