I'm looking for some demo restrictions for my object generator plugin. the plugin generates a polygon object from splines.
I found out, that I can prevent rendering by reacting to the MSG_MULTI_RENDERNOTIFICATION message. But more important is it, to prevent making a "real" polygon object using "make editable" or "current state to object". Unfortunately there isn't any message incoming before C4D makes the conversion.
Now I found out, that the thread pointer I'm getting from the HierarchyHelp pointer (hh->GetThread()) is always NULL, when executing one of the conversion.
What do you think, is it safe to rely on this behaviour?
Do you have another idea doing the task?
Thanks in advance,

Hmm, try to check what Flag is set in hh->GetVFlags(). I could imagine that the object will have VFLAG_POLYGONAL set when converting. Just a guess.

yes, VFLAG_ISOPARM and VFLAG_POLYGONAL are set. I tried to erase all flags with hh->AddVFlags(0). Although this function is named "Add..." the sdk says "Change the virtual object flags". But the call has no effect. I call the function in GetVirtualObjects(). Maybe too late?
Where can I manipulate these flags? Is it possible at all?

I don´t think you need to change the flags at all. I just thought it would be helpful in checking when to return something in GetVirtualObjects or not. But now that I think about it, I don´t think it´s safe to use these flags.
Sorry, don´t know anything else spontaneously.

It seems, that the *baseThread == NULL check works fine. Even when trying to export the document as 3DS or putting it into e.g. a hypernurbs and convert this, the method works! I'll keep an eye on it and test it on different platforms and c4d versions.
