Material operator

Material​

Overview​

The Material operator uses a designated Material ID from the input segment and replaces it with a new value identified in the From/To range. If the From and To value are identical, the ID is simply swapped for a single value. If the From/To values form a range, then the operator can either replace the IDs in a looping sequence or pick values at random.

note

This operator is only compatible with V-Ray. To use with other renderers it is necessary to disable Display > Use Instancing Engine. See Best Rendering Practices for more information about the rendering modes.

Usage​

A single Material Operator is used to reassign a material ID from the input Segment.

If you would like to reassign multiple IDs in the same segment, several material operators can be wired in series, each controlling a different input ID.

Interface​

Random. selects a value at random between the From/To ID range.

Sequence. cycles through the From/To ID range values, looping when it reaches the end.

From/To. Defines the start and end values of a range for the Material IDs.
