    I'm genuinely surprised at how well K-Cycles runs on my old 1060 - I can only imagine what it would be like if I weren't cheap as can be and updated it! But the whole thing is fantastic, and I love it. It installed seamlessly, and as far as I can tell, isn't having any issues with anything else I've got installed in Blender. Cut render times down to a fifth of what they were on the project I'm currently working on. Also, the Ultra Lighting system is fantastic for organization and efficiency, and the built-in Post FX are intuitive and easy to use in a way that the compositor has never been for me. Will definitely be back for an updated version in 2023!

    I WANT TO MAKE THIS CLEAR. I went to blender artists, I saw multiple posts people asking about this sussscription heist when I was researching for just one leap of purchase that I could afford during a sale...nothing. he said nothing. I just assumed it wasn't even a question. NO. who would do that for such a basic renderer.
    WELL I DIDNT SEE IT COMING IT IS NOT CLEAR AT ALL QWHAT WE WERE GETTING INTO.
    MAKES ME SICK WHEN I SEE "I HAVE POURCDHASED THIS! go to my orders.... oh no I havent/ PYSCH! I just had an uplifting moment until I saw that VBLENDER MARKET DOESNT KNOW HOW TO ADVERISING THISW SUBSCRIPTION CRAP. NO I HAVE NOT PURCHASWED THIAS. FIXS THIS STUPIPD DISPLOAY OF WHAT I HAVE PRUCHASED> svcrew the type fixing

      It Is not exactly a subscription, since K-Cycles will always work and available for download. What stops are the updates and new features at the end of the year. It is clearly states on your right where the product is selected with the price and the product name has the year. It's also mention in the FAQ section. It is has never being hidden and questions about it answer truthfully.

      K-Cycles is not an add-on is a custom blender build and I believe the only one in Blender Market. Add-ons requires very little or no work to update, since blender python API has small changes between blender version updates. Even then many less popular add-ons stop being updated and don't work anymore due to low new sales and the developer can't work for free.

      K-Cycles custom builds add features not possible with add-ons. The update requires a lot of work their are about 1000 source code changes each new blender version that need to be integrated into K-Cycles. Builds for each platform Windows, Linux and Mac plus the cost of separate hardware. In addition the work of adding new features and support. Just look at my youtube channels and check all the features I added this year.

    My add- on does not work and the discord link to ask for support has expired. This wasnt a cheap add- on so feeling like i've been robbed. :[ Please let me know where users can reach support

      This customer after this post got quick support and help through Blender Market "Ask a Question". The discord link for K-Cycles channels should be working, but it is not official support.

    The price is an annual plan I was not aware of that when I ordered the product in November 2021 (I paid 36$, I don't remember if it was a discount price). Now if I want to get the 2022 version I have to pay once again 44$ (includes 20% OFF for people who purshased 2021 version). This should have been clearly mentionned in big red characters at the beginning of the product description. I would have been aware that when I was purshasing the 2021 version, I will have to pay once again and for a higher price every futur years. Thus I would not have ordered the product and try to find another addon because I'm not sure that there is any other addon on blender market for which customers have to pay every year, this is definetely an annual plan business model.

      1. K-Cycles is not an add-on it is a custom build offering features not possible with a regular add-on. K-Cycles is the only custom build product in Blender Market. Custom build requires considerable more work to update and maintain with each blender version and platform Windows and Linux.
      2. It clearly states that updates are free until the end of the year on your right where the product is selected by the price and also in the FAQ.
      3. Thanks for your support.

    K-Cycles is integral to my workflow where I create long animations on a monthly basis. I can render beautiful Cycles frames at a high quality while gaining significant frame time savings of around 10s-20s (which is around 40% of my normal Cycles render time).

    I have to say that this product is perfect even when it is not actually add-on. In new version 3.2 coming "ultra lighting" is game changer for my needs (now it is in beta). Regarding payment every year for upgrade, well if the K-Cycle brings me every year something useful like "ultra lighting" it is more than acceptable.

    DO NOT BUY THIS PRODUCT UNLESS YOU WANT TO PAY ANNUALLY. Why doesn't the developer list this as an annual paid subscription? Because that's what it is. I've made dozens of purchases on this site and this is the first time I've ever felt morally compelled to write a negative review. So here goes... I bought K-Cycles 2021 at the end of August 2021 and the last version I'm able to download is from December 2021. I had less than 4 months before needing to pay to upgrade again. 4 months! No other addon I've purchased has done anything like this. And to mock me further the K-Cycles 2022 page says I've already purchased the product. Yes, an unsupported product named similarly but not the product. This developer is a doing some terrible, shady business practices. To put it in perspective, if you had bought the 2021 version in December 2021 you would have been able to download less than one month of updates before being hounded in email to pay to upgrade. No matter what the developer says to justify their greed it's just useless excuses. They can go pound sand.

      1. It is not exactly a subscription since the K-Cycles 2021 product does not expire, is always available and support continues. The updates do stop at the end of the year.
      2. It clearly states that updates are until the end of year on your right where the product is selected by the price and also in the FAQ.
      3. I do not sell the product directly it goes through Blender Market unfortunately they don't have yearly subscription setup.
      4. I offer high discount towards the end of the year to compensate and switch to a new version a couple month before the end of the year.
      5. Creating custom builds for Windows and Linux adding new features and regular updates for the alpha/beta/release versions with customer support. Takes a lot work compare to a regular add-on. Just look at the new performance and features added in the last few months.
      6. Appreciate your previous support.

    I bought K-Cycles 2021 and now, if i want anything newer than 3.1 alpha i have to pay the best part of $40 again? No thanks. A 20% discount for previous version buyers? No thanks, a 70-80% i would think about it. Instead i will give Turbo Tools V2 a try. At $25 on Gumroad, i think it is a better proposition . It is an addon, so no need to have separate installations, or wait for the latest version to be ported. I do appreciate the efforts of the developer, and understand we all got bills to pay, but like Sam said, i do feel cheated out of $40. The product itself is not too bad, it crashed a number of times, but so does vanilla blender. Slightly faster and better denoiser but nothing to justify an annual subscription, which is what this is.

      K-Cycles has many advanced features that are not possible with an add-on for example real-time viewport, "Post FX", the very well receive "Ultra Lighting" , "Ultra Denoiser" is faster in native C++, better Cycles performance and other features.

      A custom build like K-Cycles takes a lot more effort and time to update, add new features, and build multiple blender versions for various OS that an regular python add-on.

      At this time I am offering 25% off + 20% discount that is almost half price from the regular price which is a great value.

      Can also use the denoiser/render preset add-on together with K-Cycles for maximum benefit.

    This is not a regular add-on, instead, it is a custom and completely separate custom blender installation. Your previous Blender settings and your old add-ons will need to be reinstalled in the k-cycles instance.

    The performance increase was also not that noticeable and the viewport had strange artifacts during initial samples.

      The previous Blender system settings needing to be reset is rare, but it would only need to be done once. This can also happen to vanilla blender.

      Performance improvements could be configuration issue or hardware and scene depend.

      The Viewport mode is set for faster performance, but can be change easily by enabling "Extra Viewport Updates & Navigation" is slightly slower performance, but better navigation and cleaner initial samples.

      Installation manual has a complete troubleshooting section. I offer direct support for any issue that can happen and most cases are easily resolve and many are not K-Cycles issues.
