Rewrapping V4.2's eyeBrow mesh to an externally morphed Head

duane_moody

I'm working on a Victoria 4.2 character whose head isn't exclusively the result of Head dials, and realized that the eyeBrow mesh only "knows" what the Head dials have done to alter the Head mesh. As a result, the eyeBrow mesh is largely out of sync with the Head it covers. Is there a utility to re-shrinkwrap the eyeBrow mesh to the current state of the Head, following the same offset from the Head's geometry?

Otherwise, I need to determine the offset value for the vertices, generate a translation table correlating the vertices of eyeBrow to their corresponding Head vertices (eyeBrow is essentially a material prop with its corners 'rounded') and then write a script that outputs a morph target for eyeBrow.

If the utility doesn't exist I'll set about writing it, I'd just like to avoid duplicating someone else's work.

Well, you could morph the brow to fit then use Morph Loader pro in DS with Reverse Deformations to subtract the contributions from the standard morphs - I think there's a Poser script with similar function, but I can't recall name or author.

As you might have guessed, I attempted both and the results weren't particularly satisfactory. I'm trying to restore the same level of conform that Vicky's brow mesh has out of the box.

This sounds like it would only be practical for a head whose transforms were the results of dial morphs – which wouldn't be necessary to correct because those already automatically mimic on the eyeBrow mesh. If I misunderstood what you meant here, I apologize; I haven't used D|S extensively yet.

Thanks for the feedback, though. The most arduous part of writing this utility is going to be creating the vertex translation table: the brow vertex order is nearly random and I have no reason to expect it to follow the same order in a larger object like the head (esp. since .obj spec doesn't require any order to the vertex cloud). Then again, it's only ~800 vertices and the mesh appears to have point symmetry, halving the workload.

If a DAZ engineer has any insights into this, I wouldn't mind hearing them.

How about this:

I haven't actually used it but it seems to do what you're describing.

The big question I have...are you actually using it for anything?

The vast majority of V4 textures have the eyebrows on the face map and turn the 'brow' surface to 0% opacity...
