Generates scenes suitable for rendering shader balls with Appleseed.
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
The output scene.
The on/off state of the node. When it is off, the node outputs an empty scene.
The shader to be rendered.
The resolution of the shader ball image, which is always a square.
An environment map used for lighting. Should be in latlong format.
The maximum number of samples used by appleseed to render the shader ball. A value of 0 disables the limit.
The number of threads used by appleseed to render the shader ball. A value of 0 uses all cores, and negative values reserve cores for other uses - to be used by the rest of the UI for instance.
