ArnoldAttributes

Applies Arnold attributes to objects in the scene.

user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

out

The processed output scene.

enabled

The on/off state of the node. When it is off, the node outputs the input scene unchanged.

in

The input scene

filter

The filter used to control which parts of the scene are processed. A Filter node should be connected here.

attributes

The attributes to be applied - arbitrary numbers of user defined attributes may be added as children of this plug via the user interface, or using the CompoundDataPlug API via python.

attributes.cameraVisibility

Whether or not the object is visible to camera rays. To hide an object completely, use the visibility settings on the StandardAttributes node instead.

attributes.shadowVisibility

Whether or not the object is visible to shadow rays (whether or not it casts shadows).

attributes.reflectedVisibility

Whether or not the object is visible in tight mirror reflections.

attributes.refractedVisibility

Whether or not the object is visible in refractions.

attributes.diffuseVisibility

Whether or not the object is visible to diffuse rays - whether it casts bounce light or not.

attributes.glossyVisibility

Whether or not the object is visible in soft specular reflections.

attributes.subdivIterations

The maximum number of subdivision steps to apply when rendering subdivision surface. To set an exact number of subdivisions, set the pixel error to 0 so that the maximum becomes the controlling factor.

Use the MeshType node to ensure that a mesh is treated as a subdivision surface in the first place.

attributes.subdivPixelError

The maximum allowable deviation from the true surface and the subdivided approximation. How the error is measured is determined by the metric below. Note also that the iterations value above provides a hard limit on the maximum number of subdivision steps, so if changing the pixel error setting appears to have no effect, you may need to raise the maximum.

attributes.subdivAdaptiveMetric

The metric used when performing adaptive subdivision as specified by the pixel error. The flatness metric ensures that the subdivided surface doesn’t deviate from the true surface by more than the pixel error, and will tend to increase detail in areas of high curvature. The edge length metric ensures that the edge length of a polygon is never longer than the pixel metric, so will tend to subdivide evenly regardless of curvature - this can be useful when applying a displacement shader. The auto metric automatically uses the flatness metric when no displacement shader is applied, and the edge length metric when a displacement shader is applied.

global

Causes the attributes to be applied to the scene globals instead of the individual locations defined by the filter.
