E-Cycles - Celebration Sales with 77.7% off until the 17th of June!

New weekly builds are available.

Edit: a dll was missing, it’s now fixed.


The builds for OpenCL/CPU rendering are coming, including the new denoising node.
Although it’s intended for stills, the new denoising at 36spp looks like that in videos:

Stay tuned.

The OpenCL and CPU build will be available soon.

Question?: Could you make 4 renders of the same still. 26spp, 72spp, 130spp, 260spp. I think any denoiser for pro use in the end is to eliminate the small noise.

E-Cycles for CPU and OpenCL at half the price is now available. You can see a comparison of the denoisers here E-Cycles for CPU and OpenCL with new denoiser

Edit: Merged back with the original E-Cycles, so their is one product for all devices. (with still the choice between 2.8 and 2.7)

Here are some examples of the 2.78 splash screen by Juri Unt (www.cgstrive.com)

If you want a version for CUDA, which is also 2x faster to render than official version, you can get it here for 2.8 https://gumroad.com/l/tsTuV or here for 2.7 https://gumroad.com/l/SeYhy

You can also see a video of classroom made at 36spp here E-Cycles - sales coming on 4th of April and Mac 2.8 version available

If you want to learn how to add such functionnality, make rendering faster, add new modifiers and create your own Blender, you are welcome to take part to this course: https://gumroad.com/l/ecycle/kn67150 :slight_smile:


So, if I currently have the CUDA version, can I access to this one for free?


Yes, the OpenCL improvements are already in the CUDA version. For CPU, their is a beta build at the bottom of the CUDA product page.

Eager to see this develop further. And cool to see the split.

you should work for blender institute


I have merged your most recent thread with this one. You already have an active thread for E-Cycles. You don’t need a new thread to announce updates to it, no matter how dramatic.

It’s was a separate product actually. But I merged it back also on Gumroad now. So there is only 2.7 and 2.8 version again. Note that CUDA remains the focus of E-Cycles for now, the speedups in OpenCL and CPU rendering are bonuses.

Dithered sobol is fixed, new builds are coming soon.

i need to know if you are deciding to continue splitting up the plugin because that is a huge red flag for me, i expect to pay for it and get everything in one package. its kind of a bad move to have a separate product instead of raising the value of your current one.

It was a split only for people not needing the cuda improvements. All the improvements to OpenCL were already from the begining in E-Cycles, just not used by anybody because the small 10-20% speedup was not worth the price for many. With the new denoiser, some asked for a lower price for those only needing a part of the features. So it was just intended to make it more accessible for low budgets. For CPU, their is a separate beta build also already available on the product page. Anyway, the splitting is over. So everything like before :slight_smile:

By the way, since release, E-Cycles got:

  • about 5% faster rendering
  • a new sampling algorithm to reduce the needed samples by about 20%
  • a new denoiser.
  • an optional beta cpu build.
    And that although I said there is only one feature update per month. So I indeed raise the value of E-Cycles regularly, you got the double of what was planned until now :wink:

Wow. Thanks for your work on this. It’s blazingly fast and I’m happy to be able to support your efforts.

Some things I’ve noticed / questions I have:

  • Auto-tile size seems a bit off with the denier turned on. I’m using CPU/GPU to render. When I turn on auto-tile, it wants to do 256x256. That leaves a lot of tiles still rendering on my threadripper, waiting to denoise, all while the GPU sits doing nothing. I set it to 32x32 and I get much better performance (even then GPU only at 256x256).
  • Octane just got a pretty big performance boost by using RTX cores for ray tracing. Any chance you’ll be implementing anything similar?
  • Any chance for a Mac version? I have a couple Macs that it would be great to throw into the mix via Crowd Render, though I can always set up boot camp.

Thanks again.

You’re welcome :slight_smile:

  • Auto tile size is optimized for pure GPU rendering. CPU rendering only likes 16x16 max 32x32, so it doesn’t really need a smart decision, you can just leave it at 32x32 to be more gpu friendly and forget about the tile setting. Note also that their are beta builds for cpu on the product page. They are not supported yet, but bring good speedups on ryzen (17% on the BMW scene in my case using a ryzen 2200g).
  • RTX is on my todo list indeed, but I prioritize optimizations that work on older generations to benefit everyone.
  • I’m working on a mac version. But indeed, Macs are dropping all APIs but Metal, so if you can boot Linux on it, it’s the best way to go on the long term anyway.

Do you think it would make sense to start crowdfunding to hire a few developers to make a Metal version of Cycles/E-Cycles at reasonable timeframe?

For it to work you would need:

  • devs who know Cycles and have time free (I don’t know any personnaly) and are willing to invest time learning an API that work on a single platform where 10% of the user base is and are ok dealing with graphic driver that were barely debugged because few applications use metal. You can also take a random guy, but then chances that it fails or takes much longer are high.
  • at 5K/dev/month, if you find 100 mac users who want to donate to port cycles, it’s still 500€/month/donator for one dev. If you want it to be done faster (like Eevee has about 3 devs for 2 years?) you multiply that by the number of devs.
    Even if it succeed, the code base has to be updated regularly, so even after commit (if it’s accepted), you would still have to pay as it’s otherwise more maintenance work for the core devs, which is unlikely to be welcome given all the pending changes for 2.81, 2.82, etc.
    So it’s a rough guess, but I see like 1% chance it happens.

Or with all that money, you could buy a very good Linux render farm with 4 gpus and give some money to current effort to make Cycles faster on Linux and Windows. That would also motivate your brand to support cross platform APIs.

Thank you for your comprehensive response.

Regarding another systems - If I used only Blender I’d have been working on Linux for a long time. But there is no sensible alternative for Apple Motion, Logic, FCPX, Affinity, Tumult Hype and a few more on Linux. The only option is Windows. Unfortunately.

Then Windows, it supports cross platform API :slight_smile: The only thing they understand is money. If people buy product from other vendors, they will think twice before trying to lock their customers.
