Many thanks for the reply, DavidGB.

As you can see, your solution works.

At least I have the head size, arm and leg lenght as well as foot size (more or less) working.

I don't think I want to do DAZ' job and add all the scaling zones as it requires not just creating the zones but also carefully weightmapping them.

But it's enough for now to fool around with Genesis a bit until an official fix is released.

Thanks again.
