GetAndCheckHierarchyClone & subdivision surfaces ?

    I have this code snippet in my def main(), that I use to get the child (parametric) object and convert it to a polygonal object to make further modifications. This way I can make nondestructive generator/editor that works fluently with parametric objects as well.

    However, when I place a subdivision surface as a child object, this bit does not work. The result is never a polygonal object but always a BaseObject.

    What can I do in this case?

    child = op.GetDown()
    polyobj = op.GetAndCheckHierarchyClone(hh,child,c4d.HIERARCHYCLONEFLAGS_ASPOLY, False)

    Tried many things, I can't get the poly representation of a subdiv. surface :(

    Hello,

    Are you using this code in a Python Generator? Please always include the context of your code and your question.

    As described in your other tread ("Custom Subdivide Generator"), GetAndCheckHierarchyClone() does not return an object but a dictionary. Using the "clone" index I have no problems to access the polygon version of a child subdivision surface.

    Yes this is a python generator,
    can you post a code that "works" ? When I try to get the poly representation of the child subdivision surface all I get is:
    <c4d.BaseObject object called 'Subdivision Surface/Null' with ID 5140 at 0x000000E56BA8D150>

    which is a base object

    Hello,

    this code works perfectly fine for me:

      
result = op.GetAndCheckHierarchyClone(hh,child,c4d.HIERARCHYCLONEFLAGS_ASPOLY,False)  
  
if result is None:  
     return None  
  
polyobj = result["clone"]

    Here is an example file

    As you can see the left python generator contains a subdivision object, and it's not converted to polygons.
    However I've converted the right example's content to polygonal object and it works perfectly with a polygonal operation.

    Hello,

    I can confirm some problem in your scene with the very Subdivision Surface object you use. But I cannot reproduce the behavior with a new Subdivision Surface object and a cube. Does this problem only occur with that scene or also with a new scene and new elements?

    Best wishes,

    Yes, this happens with every scene and every new element.
    Can you post the same scene made on your end, so I can test it?

    I've bean experimenting with this since we've discussed, looks like sometimes it works and sometimes it does not. Sometimes when you play around a lot with the same generator, it suddenly stops working (I have no idea why)

    Hello,

    if you can find a way to reproduce the issue we could file a bug report.

    Best wishes,
