Might I ask, what is this product on a technical level?

I see so much postings of "fix morph makers" that tell how difficult is to make "installers" for their products or ERC and such.

That made me wonder: Is this really a "problem" for you? In case you target the poser, there are better ways to install morphs to a figure and better ways to create the ERC than simple valueOpAddDelta.

Why dont you make a python script to install your morphs. You should see my posts about n-dimensional JCMs. Its all scriptable. Don't let injection and .cr2 limits slow you down.  I'd be willing to assist on a python level. Morphs and ERC is my thing.
