资源介绍：
KtoA（Katana to Arnold） 是由SolidAngle开发、Autodesk维护的专业渲染桥接插件，专为将Arnold强大的光线追踪渲染器无缝集成到Katana灯光与场景管理流程而设计。通过KtoA，艺术家可在Katana中直接调用Arnold的高质量渲染能力，全面支持其材质系统、灯光模型、着色器、AOV 输出及 GPU/CPU 混合渲染。该插件为影视、动画与 VFX 制作提供了高效、灵活且可扩展的渲染解决方案，使复杂场景的灯光与最终成像过程更加高效与可控。
Arnold for Katana (or KtoA) provides a bridge to the Arnold renderer from within the standard Katana interface.
主要功能：
- 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).
