    Howdy,

    I have a problem with my input object:

    It seems that the GetAndCheckHierarchyClone() function can only handle one type of flag from the list of flags for a given hierarchy:

    I found this thread:
    Search thread

    ... that shows how to handle multiple flags, but it doesn't work if the hierarchy in question is a mixture of different object types.

    If the hierarchy is like this:

    Plugin Object (input)
    -Sphere Primitive
    --Instance (cube)
    --Spline Primitive

    ... then the Spline Primitive is ignored

    If the hierarchy is like this:

    Plugin Object (input)
    -Spline Primitive
    --Sphere Primitive
    --Instance (Cube)

    ... then both the Sphere Primitive and the Instance are ignored.

    How can I get it to handle both flags when both types of objects are in the same hierarchy?

    Adios,
    Cactus Dan

    Can you please post some code.

    This seems to work for me:

    cheers,

    Howdy,

    Thanks for the reply, but I found the solution to my problem in your sticky thread "Poly meshes and GetVirtualObjects()". Probably should've looked at that thread in the first place. ;o)

    Adios,
    Cactus Dan
