Producing high-quality 3D renderings with physically-based, Monte Carlo 3D rendering software can be a challenge. If speed and budget are important, that means contending with noise. When high-quality renderings are a must, major financial outlays are required, not to mention waiting through slow rendering.

Altus denoising software puts an end to the dilemma between settling for low-quality renderings for the sake of speed and budget, and expending large amounts of capital for high-quality 3D rendering. Altus denoising software tackles those issues with ease – with crisp, clear, noiseless 3D rendering results, with no long waits, and with significantly reduced costs.


Altus Denoiser supports Linux, Mac and Windows and can denoise renders from all popular 3d Renderers.

Denoise with Speed

Altus Denoiser is built with OpenCL meaning you’ll get denoise results fast. Altus can fully leverage your high performance GPU or CPU setup. With preview mode you can get HD denoise results within seconds.

Preview & Production Quality

Altus can denoise at two quality levels. Preview mode brings fast results. Production mode brings the best quality.

Hair & Strand Denoising

Altus can preserve details in hair and fur. Keeping your strand definition while removing noise.

Interactive User Interface

Altus Studio is an interactive user interface that helps you import and manage Altus projects. Get quick visual feedback with the interactive image viewer.

Command-Line Denoiser

Altus ServerPro includes a command-line denoiser. It can be managed by config files, automated by popular render-farm software, and can be scripted to work your way.

Temporal Filtering for Animations

Altus can take in neighboring frames while denoising animations. This will prevent flickering and other noisy artifacts.


Remove the noise while retaining the sense of volume and turbulence. Altus preserves the high frequency details that give volumetric’s their realism.


Get sharp refractions/reflections and smooth glossy surfaces at the same time. Altus reduces the samples required to get a smooth reflection.

Subsurface Scattering

Subsurface scattering requiring too many samples? Altus can take the transmission/SSS AOV information and smooth the noise while retaining shape, color, and texture details.

Motion Blur and Depth of Field

Altus smooths out DOF while keeping foreground/background separation. With global position AOVs, Altus gains insight into the scene that other denoisers lack.

Denoising Textures

Remove the noise while keeping texture details. Colors, Normals, Displacement, can be preserved, keeping your material definition the way you want it.

Denoising Global/Indirect Lighting

Have noisy lighting? Altus can denoise your AOVs too giving you smooth global illumination at a fraction of the samples.

Denoising all AOVs

Altus can denoise all your AOVs simultaniously. With Altus you can select which AOVs to input to Altus and a different set of AOVs to denoise.


Obtaining high quality 3D renders used to involve waiting and waiting through slow rendering cycles. Altus denoising technology dramatically cuts the wait. The secret: Altus allows users to generate fast, noisy initial renders with fewer samples per pixel (SPP), and then denoises those initial renders to produce high quality images and animations.


As a post-process tool, Altus integrates into your existing production pipeline and workflow. We work the way you want to work. Altus works with any Monte Carlo 3D renderer, and works well with industry-standard automation tools.


Producing high-quality 3D renders used to mean making a significant financial outlay. But with Altus, high-quality 3D renders are actually budget-friendly. Adding Altus to a company’s existing rendering technology reduces costs significantly. Cost reductions occur for personnel associated with rendering, avoiding expanding your server farm, and Information Technology (IT) maintenance. Customers report time savings as high as 50 percent which translates to cost savings. That’s huge.


All Altus downloads, including our SDK, are free for evaluation purposes, but insert a watermark over your render. To remove the watermark, purchase the licenses you'll need to get your project finished quickly.
