      the cloner has nothing to do with it. the objects *die* as soon as you try to csto a hierarchy which has a null object at top level.

      this will return 6 dead SplineObjects ( "Null" is passed to SMC) :

      while this will return 6 perfectly healthy SplineObjects ("Flower" is passed to SMC) :

      but the funny thing is, even if i convert the parametric spline inside the cloner into SplineObject,
      SMC still returns "dead" objects.

        In your inexclude list try pick objects with doc as None
        Sebastian once showed that (but can get "funny" in expressions)

        obj = InExclude.ObjectFromIndex(None, i)
        

        And as for "obj is not alive"
        you may need to work on a clone instead in your CSTO.

          hey,

          thanks for your reply. when i change

          obj = InExclude.ObjectFromIndex(doc, i)
          

          to

          obj = InExclude.ObjectFromIndex(None, i).GetClone(c4d.COPYFLAGS_NO_MATERIALPREVIEW)
          

          it doesn't change much. the smc returns one dead spline instead of the amount set in the cloner. is 
          cloning meant in a different way ? i have to admit i always kind of ignored that topic "clone xyz, or it 
          will blow up into your face", as it didn't really caused me any trouble in the past, even if the sdk said 
          so 🙂

                It's living on the edge modifying the document at runtime.
                Generally do this in a command (that you call from your xpresso node (havent tried))
                or in a message body of an expression (so you can control the document while executing)

                  thanks for your help. with "do this in a command" you suggest using a CommandData plugin ?

                      hm,

                      doesn't change anything.

                      - script version
                      - more explicit usage of SMC CSTO
                      - did the clone object/document thing the sdk suggests for CSTO

                      something doesn't feel right, i am either making a fundamental mistake, or smc is bugged (again)
                      at that point. never had to do all this cloning stuff in the past. there is also the fact, that when you 
                      start cloning things before smc (the object, the document or both) the smc just returns one object.
                      or in other words - is just ignoring the cloner (although I explicitly set NOGENERATE to False in its
                      settings).

                      i am also pretty unsure about this documents.IsolateObjects() method thing. do i have to search 
                      my objects in the document by myself or is the passed object list now automatically referencing 
                      objects in the new document ?

                      edit: just for the record - console output for this is :

                      smc <c4d.BaseObject object called 'Cloner/Null' with ID 5140 at 0x0000000006E180D0>
                      <dead c4d.SplineObject object at 0x000000000FD185F0>
                      

                      edit no. 543957 :

                      also the whole - cloner objects aren't the cause for dead objects, but null objects thing applies also to this script version.

                        But once the list is returned to main(), splines are no more valid because they were stored in a local list and they don't belong to any document.

                        To resolve this, you should create a new document in your main() and then pass it to getSplines() in order to insert the resulting object for SMC CSTO.

                            But once the list is returned to main(), splines are no more valid because they were stored in a local list and they don't belong to any document.

                            To resolve this, you should create a new document in your main() and then pass it to getSplines() in order to insert the resulting object for SMC CSTO.

                            this solved my problem, thanks 🙂
