BluEcho,

Quote - My Antonia morphs were made with magnets and the putty tool.
So I guess if she were a V4 I could still distribute them?

Unfortunately it is not always as simple as that.

Some figures load with one or more morphs already expressed. I remember that V2 loaded with a head morph expressed, and I think V3 loaded with an eye morph expressed. It's very easy to miss things like that, and include them in your own morphs by mistake.

Many figures these days have Joint Controlled Morphs. If your figure is not in a zeroed pose (usually different from the default pose), and you make an INJ, it is possible that you will include some of the JCM in your morph. It is even theoretically possible for a JCM to be expressed when the figure is in a zero pose. Whilst the morph police are hardly likely to break down your door because you occidentally included some JCM, these things can can corrupt you own morph, and lead to a less than optimal result.

If you are creating or exporting your morphs from within Poser; the sure fire way to be  certain that your morphs are not corrupted is to start with a cr2 that has had all the morph deltas deleted from it!

I know this is a somewhat depressing answer, and only raises yet more questions. As the answers to those questions can be a bit long winded, perhaps this thread is not the best place to go into them, as it might take the thread too far off topic.
