What is K-Cycles?
K-Cycles is a highly optimized custom build of Cycles render engine, ultra lighting, post FX, ultra denoiser, camera settings, multi-camera render, camera override and realtime viewport lighting and effects for Blender. It is fully compatible with Cycles and designed for Nvidia GPUs. Features include:
Ultimate rendering performance for viewport and final renders.
Amazing Ultra Lighting the most powerful and complete lighting features for Cycles.
New Ultra Denoiser with the latest Intel denoiser technology and multi pass for clean and super sharp images.
Ultra Denoiser works inside Blender without needing the compositor and has great performance avoiding complicated compositor nodes.
Animation Denoiser uses the latest OptiX temporal denoising to improve animation render times.
Even faster renders using intelligent scene and settings optimizations preset modes with higher K-Cycles performance while still maintaining good image quality.
Amazing viewport Ultra Lighting, Post FX including BLOOM effects, FLARES with glare, anamorphic and ghosts, Tone Mapping and Lens effects that elevates your art to the next level.
Camera mode/override for Ultra Lighting, Post FX and Output Resolution.
Render Cameras for rendering individual cameras to the image editor or to automatically save file render.
All K-Cycles Ultra Lighting and Post FX effects are animation ready with all the settings fully keyable and with previews on the viewport.
The K-Cycles Ultra Lighting, Post FX effects can be done in the viewport or final render both in GPU or CPU.
Cycles image quality with less render noise.
Fully compatible with Cycles and all Blender addons.
Regular stable release and alpha builds updates with the latest features from the Blender.
One version optimized for both Optix and Cuda.
Easy to use without the need of changing Cycles settings for fast performance.
K-Cycles Performance
K-Cycle performance mode.
GPU Boost.
Global Illumination presets.
Sampling render presets.
Optimize viewport updates.
A set of Cycles performance features and options for improving the Cycles viewport and final rendering. The K-Cycles performance mode for maximizing the rendering time. GPU Boost controls Cycles GPU memory to help improve performance and memory usage. Global Illumination presets allow scene lighting settings for faster rendering or higher lighting quality. Sampling final render presets is the best way to control the render time, noise level and scene image quality. Reduce viewport updates for faster viewport rendering.
The performance chart below compares K-Cycles to the same Cycles build of Blender. Tests done with the default Cycles final render settings of noise threshold of “0.01” and samples of “4096” without denoiser.
Videos on K-Cycles Performance:
K-Cycles Performance Limitations:
K-Cycles will not improve time for scene loading, textures, synchronization, particle generation, BSP, or other pre-rendering calculations.
K-Cycles performance gains will be minimal at low render samples or high noise threshold above 0.05. In this case it is recommended to use “Ultra Denoiser” to improve scene texture and geometry detail, and image quality that requires considerably less render samples compared with the standard denoiser.
K-Cycles performance gains can not be guaranteed due to differences in graphics hardware, system configuration, render setting or specific scene issues.
K-Cycles Physically Based Light and Shadow Linking
Physically based Light linking per objects/collections.
Physically based Shadow linking per objects/collections.
Invert light linked objects/collections.
Lightgroup shadow casting.
The new physical based light and shadow linking. For the ultimate creative control of the lighting and shadows of the scene to bring your art to the next level.
K-Cycles Camera Mode/Overrides
Individual Ultra Lighting settings per camera.
Individual Post FX settings per camera.
Individual Resolution/Frame Range settings per camera.
Instantly switch between global scene settings or individual camera settings for Resolution/Frame Range, Ultra Lighting or Post FX by enabling the camera icon.
Ultimate control for all your K-Cycles settings per individual camera. Instantly switch in the viewport and final render from default global scene settings for Ultra Lighting, Post FX or Resolution/Frame Range to a per camera setting by just clicking on the “Camera Icon”. These adjustments are done in real-time without re-rendering. By duplicating cameras can explore multiple lighting and post fx variations of the same camera with instant comparisons. Allows full customization and artistic control of the multi-camera setup in the scene by just enabling the camera icon see below for the UI.

Post FX Mask, Viewport Match and Presets
Mask allows to include/exclude objects and collections to have the specific Post FX applied.
Presets saves the Post FX settings and are like other presets used in Blender
Changes the Cycles preview to match exactly the output resolution.
Post FX Mast. Allows to include/exclude objects and collections to have the specific Post FX applied. Quite Useful for controlling which objects to apply the bloom and flares, or tone mapping for visual importance.
Post FX Presets saves the Post FX settings and are like other presets used in Blender. On the right of the Post FX header or individual effects like Bloom or other effects is the preset button. The Post FX preset button adjusts the settings for all the Post FX. The other individual effects presets settings are specific to that effect only.
Post FX Viewport match to output resolution. Changes the Cycles preview to match exactly the output resolution. This is very useful for pixel based effects like Bloom and Flares because the amount of the effects depends on the render resolution. While in this preview render mode it is possible to make adjustments exactly like they would appear in the final render. It will also disable viewport selected outlines for better visibility. This feature can have other uses for better accuracy in adjusting materials, depth of field, etc.

Post FX Bloom
K-Cycles Bloom is the only Cycles implementation of Bloom in the viewpoint.
BETTER implementation of Bloom than the compositor, many more controls for manipulating your bloom PLUS more accurate bloom as well.
EASY to use and works just like you would expect.
A feature that Eevee users have used and enjoyed is now available with K-Cycles. Dynamically interact with the scene in the viewport. Adjusting quickly the Bloom settings with fast performance in the preview render viewport. Creating beautiful Bloom effects in no time. The Bloom settings has all the options that are needed to design and easily create and customize your Bloom effect.

What the Artists Say
Jerry Perkins (masterxeon1001) hardOps and boxcutter creator
“K-Cycles provides an alternative way to utilize the power of the RTX in ways vanilla Cycles cannot. From the moment you begin rendering with it you’ll notice an immense difference in speed and performance. I am proud of the work that has gone into optimizing such a classic renderer. Even in a post EEVEE work Cycles can prove itself competitive and giving a result that just can’t be matched. And with K-Cycles you’ll get there in a fraction of the time”
Chipp Walters (chippwalters) KIT OPS, SYNTH, BEVEL, BATCH, SMART SKETCH, CHALK STYLE PRO, QUICK SHOT, EEVEE Materials System and SIMPLE TABS creator
“I created the very first course on Interior Rendering with EEVEE, and what luck it was to have Eric as a beta tester. There is no one who knows more about Interior Rendering in Blender, both EEVEE and Cycles, than Eric. His technical expertise is unsurpassed. So, when he asked me to test K-Cycles, I jumped at the chance. Most will tell you I almost always render in EEVEE– but not anymore. I can’t believe the speed increases I now have rendering in K-Cycles. It’s a must have for any serious Blender artist!”
Andrew Markert (GREEZYBEAR) KPACKS creator:
“K-Cycles has been an awesome addition to my workflow by utilizing my GPU in order to render Cycles. I have a Nvidia RTX Titan graphics card and this is such a LEAP from CPU rendering to now GPU rendering! My render times have increased 3-4x faster than my current Blender 2.91. I feel this is a solid build and runs very smoothly. The image quality is also better to me and the viewport display has much more detail in it when in dev and render views. I am seriously impressed with the render times in K-Cycles and would definitely recommend this to anyone who loves to use the GPU for rendering!”
