Arnold for Katana (or KtoA) provides a bridge to the Arnold renderer from within the standard Katana interface.

* Bundled Arnold, shaders, and plugins for a smooth out-of-the-box experience.
* Support for the latest Arnold 4.2.x series.
* Improved interactivity for live rendering (IPR) allows look changes to be rapidly previewed.
* Ultra-fast OpenVDB volume rendering.
* Shader networks.

* Render outputs and AOVs, including Deep EXR.
* Supports the curves location type in Katana for hair rendering.
* Many light types and light filters supported, as well as interactive modification of lights.
