See Polygons in the Arnold User Guide for the full documentation of Arnold polygon shapes and parameters.

_{noise -> standard_volume.displacement. step_size: 0.1, volume_padding: 0.05.}

When the step_size is positive, it turns a polymesh into a volume and its value is used as the base step for raymarching the volume.

The mesh should be closed and not have anything self-intersecting, otherwise, the volume may not render correctly.

Note:

You must add a step_size value and assign a standard_volume shader for the mesh to render as a volume. A tutorial that covers how to render a polymesh as a volume can be found here. More information about volume step_size can be found here.
