Denoise – Immediately denoises all denoisable elements using the most advanced denoising mode that is available for the image. Denoise Amount – Mixing coefficient between the original (noisy) and processed (non-noisy) image. It allows fine-tuning the effect strength to find the sweetspot between preserving the finest details and removing excessive noise. Custom DenoiseAll – Selects all items for denoising. None – Unselects all previously selected items for denoising. Inverse – Inverts the current selection. Elements that cannot be denoised are not listed. |
Denoise Mode – There are 4 denoising options available. Denoise amount option can be used later to interactively control strength of their effect. Fireflies Only – Fast filter that just removes very bright pixels from the image (created by any source - noise, caustics, sun reflections, etc). NVIDIA GPU AI – Very fast GPU-based denoiser. Available only on NVIDIA GPUs when the optional NVIDIA AI Denoiser Corona component has been installed. Intel CPU AI – (also known as Intel Open Image Denoise) Fast denoising filter applied when render ends. It is a CPU-based denoiser, running on both the Intel and AMD CPUs. It does not have any additional requirements to be executed; if the CPU runs Corona, it can run this denoiser. It is slower than NVIDIA GPU AI denoiser, but can achieve better quality. High Quantity – A more memory and CPU intensive filter that removes all random noise from the image, creating a noise-free image considerably faster than waiting for the rendering to converge. NVIDIA GPU AI mode is not suitable for denoising animation. |
Denoise Radius – Controls the radius of the denoising blurring. |
