Caracteristics and functions of Arnold

Why use Arnold?

Manage complex projects

Arnold thrives on heavy data sets and handles complex work with ease.

Render high-quality 3D images

Deliver stunning photoreal or stylized results in fewer clicks.

Get a robust set of tools

Save time with powerful shaders, operators, textures, and utilities.

Arnold GPU

Switch seamlessly between CPU and GPU rendering.

Motion blur

3D motion blur interacts with shadows, volumes, indirect lighting, reflection, or refraction.

Subdivision and displacement

Create smooth, curved surfaces with support for Catmull-Clark subdivision.

Adaptive sampling

Use another means of tuning images to reduce render times without jeopardizing final image quality.

Subsurface scatter

High-performance ray-traced subsurface scattering eliminates the need to tune point clouds.


Render effects such as smoke, clouds, fog, pyroclastic flow, and fire with volumetric rendering.


Open Shading Language (OSL) support

Use Open Shading Language (OSL), an advanced shading language for Global Illumination renderers.

Toon shader

In combination with the Contour Filter, an advanced toon shader provides a non-photorealistic solution.

Hair and fur

Memory-efficient ray-traced curve primitives help you create complex fur and hair renders.


Efficiently ray trace instances of many scene objects with transformation and material overrides.

Light Path Expressions

Get power and flexibility to create Arbitrary Output Variables with LPEs to help meet the needs of production.


Powerful denoising solutions offer you the flexibility to use much lower-quality sampling settings.
