Solid Angle Katana to Arnold v2.2.3.0 for Katana 2.6 and 3.0 Win/Linux

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

Natural integration with Katana nodes, scenegraph, and scripting.
Multi-threaded scene translation, made possible by Geolib3 in Katana 2.
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.
Works with third-party shaders and renderer procedurals (for hair, etc).
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.
Object parameters and global options better match what is available in Arnold.
Improved documentation within Katana (args files).

Requirements & Platforms
Compatible with Katana 2
Linux RHEL6 equivalent (glibc 2.12) and later
CPU with at least SSSE3 instructions (2006 and later Intel CPUs, and 2011 and later AMD CPUs)

Changes v2.2.3.0:


ArnoldLightSettings: A new node ArnoldLightSettings has been added for setting motion blur and light group parameters on lights more easily. These settings live in the arnoldLightStatements attribute group on light locations. (#253, #361)

Light group attribute: The light group of a light (for per-light AOV purposes) can be set on the arnoldStatements.lightGroup string attribute. Generally this will instead be set in the new ArnoldLightSettings node or on the light's aov attribute, but for scripting purposes this attribute is recognized by KtoA. (#253)

OpenVDB object bounds: The bounding box for the viewer for locations created by ArnoldOpenVDBVolume and ArnoldOpenVDBSurface will still be created even if no channels are specified; it will create a bounding box over all of the channels found in the VDB file. (#238)

Bug Fixes

#323 Inconsistent crypto_material output due to multithreaded scene translation
#350 Auto-wired surface shaders in gaffer inherited in light filter children
#356 Vertex scope without indexed values get dropped
#357 ArnoldStandin node not recognizing gzip extension
#360 Error setting imageSearchPath in ArnoldYeti
#366 Procedural args type hinting broken for non-scalar values

Do you need a Sound Editing category (audio soft, samples, etc)?
