Richard you do know that FBM creation for Genesis isn't as 'simple' as it is for V4/M4, it's not just a case of loading in the morph and saving it, you also need to check that it works with the rig & WM, if it doesn't work you then need to adjust the rig or WM or both to get it to work, you then save that info in with the morph.

If you turn 'on' the show bones parameter and check out the DAZ own morphs for Genesis, you'll find that none of them have the same rig as the default Genesis, the basic male & female shapes change the arm,hand,collar & pectoral bones, the Gen4 shapes are also like this, which is why when you load a pose for the basic female onto Genesis when V4 is dialed the legs don't go where their ment to.

If you check out some of the character sets available you'll find that they require you to use a DAZ morph first, this is so they can use that morphs rig on their character without having to re-rig it.
