Hi guys.
The Minotaur legs are not attached to the freak. The process is called swappable geometry. So what you see white of the Minotaur legs are newly created mesh. Not a morph.

As for the files. One folder contains, the cr2 for the Minotaur, one contains the mesh.
The other files are the inject for the Minotaur head morph.

As to how the satyr is packed; I didnt pack it, daz did. Rawnrr created the textures to require the Minotaur legs. Meaning you would have to own both the satyr and the Minotaur.
Then Rawnrr, daz and I decide to pack the legs free in the satyr. So daz was nice enough to pack the legs for us.

On to using the figure all you have to do is load the Minotaur legs from characters Minotaur folder. No need to conform them.

As for using the legs with other figures. To be honest I never gave that a thought when creating them. I wish I had and in the future anything I release I will leave my self the option of being able to make a version for all characters or release the add-ons with this option. pdxjims idea is the best way to go for now. But you will need to tweak joints as the Minotaur legs do not match bones for any of the characters other than the freak.-minotaur that it comes with. But I dont think much tweaking will be required to make them work well.
By the way Jim, very nice answer.

There will be another set of these types of legs in the near future as I start to release some creatures I have been working on. If you are interested check creatures that go bump thread on the daz forum for updates

Sorry I could not be more help but pdxjims beat me to the punch.
