Features
Memory-efficient, scalable raytracer
Arnold ray-tracing rendering software helps artists render complex scenes quickly and easily.
-
Arnold GPU public beta
A beta version of Arnold GPU allows users to switch seamlessly between CPU and GPU rendering. (video: 1:09 min.)
-
Subsurface scatter
High-performance ray-traced subsurface scattering eliminates the need to tune point clouds.
-
Hair and fur
Memory-efficient ray-traced curve primitives help you to create complex fur and hair renders.
-
Motion blur
3D motion blur interacts with shadows, volumes, indirect lighting, reflection or refraction. Deformation motion blur and rotational motion are also supported.
-
Volumes
The volumetric rendering system in Arnold can render effects such as smoke, clouds, fog, pyroclastic flow and fire.
-
Instances
Arnold can more efficiently ray trace instances of many scene objects with transformation and material overrides.
-
Subdivision and displacement
Arnold supports Catmull-Clark subdivision surfaces.
-
OSL support
Arnold now features support for Open Shading Language (OSL), an advanced shading language for Global Illumination renderers.
-
Light Path Expressions
LPEs give you power and flexibility to create Arbitrary Output Variables to help meet the needs of production.
-
Adaptive sampling
Adaptive sampling gives users another means of tuning images, allowing them to reduce render times without jeopardising final image quality.
-
Toon shader
An advanced Toon shader is part of a non-photorealistic solution provided in combination with the Contour Filter.
-
Denoising
Two denoising solutions in Arnold offer flexibility by allowing users to use much lower-quality sampling settings.
-
Flexible and extensible API
Integrate Arnold in external applications and create customised shaders, cameras, light filters and output drivers.
-
Stand-alone command-line renderer
Arnold has a native scene description format stored in human-readable text files. Easily edit, read and write these files via the C/Python API.
-
Standard Surface shader
This energy-saving, physically based uber shader helps produce a wide range of materials and looks.
-
Standard Hair shader
This physically based shader is built to render hair and fur, based on the d'Aeon and Zinke models for specular and diffuse shading.
-
Alembic procedural
A native Alembic procedural allows users to render Alembic files directly without any translation.
-
Profiling API and structured statistics
An extensive set of tools allow users to more easily identify performance issues and optimise rendering processes.
-
Material assignments and overrides
Operators make it possible to override any part of a scene at render time and enable support for open standard framework such as MaterialX.
-
Built-in Cryptomatte
Create ID mattes automatically with support for motion blur, transparency and depth of field.
