int hasvertexattrib(<geometry>geometry, string attribute_name)
<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.
Returns 1
if the attribute exists, or 0
otherwise.
Examples ¶
// Determine if the P attribute exists. int exists = hasvertexattrib("defgeo.bgeo", "P");
