E-Cycles - up to 2.5x faster rendering for Blender 2.79 to 2.82

Good news for GTX graphics card users.

E-Cycles CUDA is faster or similar to Blender OptiX.
This is amazing news for users with GTX graphics cards.

Im running into a problem, I’ve been using v20190516_win for awhile. So I downloaded the newest versions, optix/cuda. And now my render times have increased, by a lot. I can’t share the scene but it’s going from 1:15 a frame to 1:50 a frame using 2 x 2080 ti’s and a 980 ti.

I also found another problem. When I import an alembic files, they turn out like this. It shows in the render.

For bugs in Blender itself, you can report on developer.blender.org. For the slowdown in your 980Ti + 2080Ti setup, I need a file. Please you the standard support ways of the platform choosed to submit it and send details like exact OS, driver, GPU model and E-Cycles version.

Sales have started. You can get E-Cycles standard 2019+2020 at around 7$ per month or E-Cycles RTX 2019+2020 at 19.95$ per month until the 26th of October.

I don’t know if it’s an error and will be corrected, anyway announced was 20% but currently you can get 25%.


I don’t see this on Gumroad(or Blender Market, but I’d rather use Gumroad). And are these going to be in US $ now or is that a typo?


the monthly option is at 15€/month on Gumroad, I was speaking of the Blender Market sales. Existing customer (your case?) got coupons per mail, valid until the end of October.

E-Cycles standard

  • 4€/month for existing customers (with the coupon for 2020 send per mail, 45€ for 12 months).
  • 7.14€/month for new customers (with E-Cycles 2019+2020 = 15 months at $119)

E-Cycles RTX

  • 12.5€/month for existing customers (with the coupon for 2020 send per mail, 150€ for 12 months)
  • 19€/month for new customers (with E-Cycles RTX 2019+2020 = 15 months at $319)


As a comparison, Octane cost 699€ for 12 months and it still doesn’t has RTX support nor 2.81 builds. On top of the stable builds E-Cycles offer weekly builds to always have the latest Blender features and improvements.

Kind regards,

Sorry, got excited when you started talking monthly prices and thought you had put up the subscription for 2020 rtx.

And don’t forget:

As a previous OctaneBlender user I can tell:

  • You don’t have the large add-ons available for materials like E-Cycles has…
    There is the LiveDB but it still crashes blender a lot, and some materials don’t work anymore
    (they just turn any object transparent ;o)

  • You need an internet connection to activate a license…
    and hopefully it automatically deactivates after quitting (in case of crash it stays locked to the machine and can’t be used on another host)

  • You need to create lights in Octane, as there are no predefined light sources…

  • Slow support…still on 2.80 beta…and as Mathieu mentioned…still no RTX though it was announced over a year ago…RTX is only available (and in beta state) in standalone Octane version.

Did last weekend (or better started ;o) a scene of our home and did two versions…E_Cycles and Octane…but soon I gave up on Octane and bought the RTX version…not only I can use all my plugins and materials…

And if you find a bug in the software…no one is faster than Mathieu to fix it :slight_smile:

just my 2 rappen (o;


Strange, today on BlenderMarket the price for 2019+2020 was around $111, now is $119.20
Is it 20% off or 25%?

I think they corrected the price they set wrong.
The other goods are the same. It’s 20% now.

That makes sense.
I see now, this thread started last year and I guess at the time it was actually 25% whereas this time is 20%

I hope many users will see all this announcement (Redshift soon on Blender, Octane soon RTX, V-Ray coming to 2.8, etc.) are marketing announcement. E-Cylces is there for real, used and recommended by many artists and is very fast for real now.


I’m interested in E-Cycles.
One thing I’d like to know is how is it integrated into Blender. I believe I have read it is not distributed as an add-on but as a separate build itself. If that’s the case, I guess that means I can’t use experimental builds with it?

What you mean by experimental builds? Branches like the fracture modifier?

And yes…there are separate builds, not an add-on like Octane…

But Mathieu releases updates at least every week…so you always get the latest and greatest with the fastest speed available…

Tip: If you go with the RTX build, you get access to the regular E_Cycles as well…so you can start with a GTX card and upgrade later with an RTX card without to rebuy the software again :wink:

But: You can do your own builds…Mathieu also supplies documentation on Gumroad on how to build your own E_Cycles version from scratch (o;



Thank you, Richard

I mean the latest beta builds (2.81, 2.82 alpha and so on)
Thank you for the info, good to know there are frequent updates.
I’ll buy E-Cycles, it seems a valuable tool to have :+1:


Yep, I advertised the extra 5% on the Blender Market, but it is corrected now. I added 25% coupons on Gumroad for those who missed: 2.8x, 2.8x+2.7x and 2.8x+RTX.


Just to confirm before I pull the trigger: if I want 2019+2020 I can buy from Blender Market. Whereas the one you linked on Gumroad is for 2019 only, is that correct?

One thing I did not understand.
This Nebulae version (only works with nebula scenes?)
Can’t use to render something else?
