osd_limitsurfacevertex

This is like osd_limitsurface but for vertex attributes instead of point attributes. See osd_limitsurface for more information.

int  osd_limitsurfacevertex(<geometry>geometry, string attrib_name, int face_id, float u, float v, <type>&result)

int  osd_limitsurfacevertex(<geometry>geometry, string attrib_name, int face_id, float u, float v, float &result[])

<geometry>

When running in the context of a node (such as a wrangle SOP), this argument can be an integer representing the input number (starting at 0) to read the geometry from.

Alternatively, the argument can be a string specifying a geometry file (for example, a .bgeo) to read from. When running inside Houdini, this can be an op:/path/to/sop reference.
