Hi maxx,

this seems to work well. However, it is not really satisfying using that hack..

Hy nux, thanx for Code. But as you say, its not really satisfying. As tcastudios wrote, doing this will have severe performance drawbacks ...

Cheers,

So we have reason to believe that there is no Cache to release for GetContour()
in a similar manner as one can do with GetVirtualObjects() by not returning
a HierarchyHelp ?

Hi,

I contacted the developers on this issue.

Here's the information I got from the developers.

Splines created though GetContour() are cached. To make this frame dependent CheckDirty() can be overloaded to set the object dirty if a certain condition has changed:

class TestSplineData(plugins.ObjectData) :
    
    def __init__(self) :
        doc = documents.GetActiveDocument()
        self.lastFrame = doc.GetTime().GetFrame(doc.GetFps())
    
    def CheckDirty(self, op, doc) :
        print "CheckDirty()"
        
        frame = doc.GetTime().GetFrame(doc.GetFps())
        if frame != self.lastFrame:
            self.lastFrame = frame
            op.SetDirty(c4d.DIRTYFLAGS_DATA)
    
    def GetContour(self, op, doc, lod, bt) :
        print "GetContour()"
        
        return c4d.BaseObject(c4d.Ospline)

This should only be done if absolutely necessary though, otherwise the spline (and all depending objects) will be rebuilt for every single view-redraw.

Thank you very much,Yannick! That is a big step in the right direction.
I will try to get all In/Excl objects within the CheckDirty() because that is
the "core" issue I have. The generator should update on the list's object's
dirty status.
I'll report how a get (or don't get! it working.

YES YES! I'm so happy that this is solved, thanks a lot.
I've posted the important parts of one plugin I'm working with.
It needs to get dirty info from objects in a In/Excl List so I
simply could loop them and check the sum against the stored dirty sum.
Then to bypass the potential problems using GetActiveDocument() (for not active document)
I simply treat the current frame as a dirty (Long) value and include it in
the dirty sum!

Could not be happier!

I've been struggling with this in C++ just a few seconds ago. I'm so happy I remembered this thread.
I couldn't find this information in the C++ docs as well. Especially because CheckDirty() is listed under methods for Modifier objects, it didn't appear to me that I need to override this method.
