I have a recurring problem with some shoes conforming properly to v4.2 with Morphs++.  I like to set Leg Length to 1.0 to get longer legs on her.  But some of the conforming shoes end up not staying properly on the feet, instead they end up being "attached" higher up on the shin.  None of the available parameters on the shoes seem to work in getting the shoes where they need to be.  Other shoes I purchased don't have this problem.  How can I get the shoes to stay conformed through this simple morph?

I don't have the Morphs++ pack, so I can't check this idea, but I think it is worth a shot. If the shoes have shin actors, try yScaling the shin actors of the shoes .

This seems to be because the LegsLength bone scale dial on the DAZ donor CR2 does not work.  Checked this just now and the dial does not do anything when un-conformed, so I don't expect it would do anything while conformed either (probably mismatched internal channel name).  As Lesbentley is saying you likely just need to un-hide the scale dials and then scale them on the Y axis.

Oh, I forgot that the scale dials might be hidden in the conformers. Thanks for reminding me pjz99. Below is the text of a pz2 (pose) file that will unhide the scale channels in the shins. If the shoes are two separate figures apply the pose to both.

After applying the pose, you may need to select a different actor, then reselect a shin in order to force an update of the parameters palette and display the scale dials. As an alternative to using the above, you could install "Show Scale Dials V4" from sharecg.com, and apply that to the shoes. As long as the shin actors themselves have not been hidden, it should do the job.
