Arnold works with a host of third party shaders, extensions and integrations which extend functionality.
These shaders, extensions and integrations are not developed or supported by Autodesk but are provided here for your convenience.

Integrated in Autodesk Maya, Golaem Crowd makes it easy and affordable to populate worlds with directable digital characters, from a few to thousands.
Shaders
A work-in-progress production shading library for Arnold. It currently contains a surface shader and a few utility shaders, and the aim is to slowly build it into a full-featured production-quality shader library.
Kettle Shaders is Kettle Studio’s in-house package of workhorse shaders and related utilities.
The Shader Collection - Essential is a FREE shader collection for Arnold and other renderers. It includes shaders of various types. From simple helpers like a clamp range shader up to a advanced fractal or DOF shaders.

Integrations
HDR Light Studio is a powerful lighting tool for Maya and is fully compatible with Arnold. Light your shots using high dynamic range softboxes, spotlights and studio lights by clicking directly on your 3D model to position light sources. An HDRI map is generated for use in Arnold’s sky dome. See the results in the Arnold interactive preview as you light.
LWtoA is a custom plugin that integrates Arnold seamless inside Layout 11, with nearly all features suported by Arnold, including interactive rendering, all Arnold shading nodes, all Arnold lights, etc.
