Usage
pointgroupmask(surface_node, pattern)
The returned string is a space separated list of group names.

Examples
pointgroupmask("/obj/model", "group*")
Returns the names of all point groups in the specified surface node which start with “group”. So this may be something like “group1 group2 group_smoke”.
