Arnold 是一款高级的、跨平台的渲染 API。与传统用于 CG 动画的 scanline（扫描线）渲染器（Renderman）不同，Arnold 是照片真实、基于物理的光线追踪渲染器。可以单独渲染出真实光照，阴影，凹凸等特性的贴图，支持Maya 2018/2019/2020 Win版本

Arnold for Houdini (or HtoA) provides a tight bridge to the Arnold renderer from within the standard Houdini interface, in a way that is familiar to both Houdini users and Arnold users in Maya or Softimage. It also enables smooth lighting workflows between Houdini and other DCC applications, since setups can be exported and shared.
