Unfortunately, an object is being created via a CallCommand() to 'Convert from Spline' and the Hair object that results isn't obvious (there may be more than one Hair object in the document). Is there any way to get the last object added to the document?

Currently, I'm considering an unpleasant method:

1. Store all current objects in an AtomArray.
2. CallCommand().
3. Compare every object in AtomArray to every object in the document to see which one isn't in the AtomArray.

Overkill doesn't begin to describe this procedure (step 3 particularly). AtomArray::Find() may prove useful here - as long as I do some extra checks for veracity (is the unfound object actually a Hair object, e.g.).

Thanks,

...maybe the answer lies in this elusive "Hair SDK" :)

I'm not making a plugin Hair object, I'm just converting an imported SplineObject into a HairObject (standard C4D Hair object - no more plugins, tyvm). All of the SDK Hair examples (all of them) are about making your own Hair plugins using the Hair SDK (Hair Object, Tag, VideoPost, etc.).

It is sooo complex to set this stuff up (the Hair Mat, Hair Texture Tag, Hair Render effect, ...) that I found a quick-and-dirty (and completely compliant) way to do it: Convert the Spline to Hair; Add a new Hair object; move the tags from the new Hair object to the converted Hair object; remove the new Hair object. Now the Material, Texture Tag, and even the Hair Render are all setup without grueling code. ;P

Your post was asking how to determine which object was created, when you sent a menu command to create it. My speculative suggestion was that if you (we) had the Hair sample/SDK source code, you might be able to create the hair object directly, instead of using issueing the ("Convert from Spline") menu command. :)

Nope. To create a standard Hair object, you can just do this:

HairObject* hobj = HairObject::Alloc();

But I have no idea how to convert the SplineObject segments/points into HairObject guides (and I'd rather not deal with it at that level if possible). Cinema 4D already does it for me - but with that one caveat. :)
