HI Cage,

Thanks for the additional tests... First off, I agree with most of your assessment of what's going on in those images (minus any doom-n-gloominess type conclusions :lol:). My comments below...

• the eyebrows (which I assume were relatively poorly matched up and/or shaped differently to start with) are clearly handled better with the closest-vert method than ray-casting - if that was the only concern, you could run them as a separate close-vert only pass, so we have a way to address that particular issue.
• the circled (above/outer brow, head-mesh) areas also clearly seem to be an issue for ray-casting at least in this setup (I'd need to look at the Antonia mesh used to figure out why that's happening for sure, but I have an idea).
• Interestingly, the 2008 (ray-cast only) handled the lips the best, given that setup (at least the lip->headskin connections).
• most of the "false hits" you see in the 2008 (ray-cast only) image look like neck/nostril/eye-socket vertices... I'd note that most (maybe even ALL) of those would go away with a simple 'tolerance' test on the distance (they'd just become failed hits... which is probably appropriate for the neck ones... things like nostrils and eye-sockets could be run using a close-vert-only pass).
• a general note... this is an UpHill test and so yours and my observations about the relative merrits of the various methods (in this particular case) may not apply to DownHill situations.

...as to whether (or to what degree) these two methods are compatible with each other as a Hybrid method - I agree with your comments about the issues seen above, but I'm not yet ready to write it off.  Keep in mind that this was only a first proof of concept attempt.  I had already anticipated a few of these situations and have a few things that I'd like to try.  One of which - are you sitting down? - is to monkey with the normals of the target mesh! :lol:.

I am going to be afk for most of the day, but I'll play around with this some tonight.  In the meantime, I think I have sufficient UpHill test info to go on, so if you get anxious (and have time) for any other testing, I'd be interested to see that same setup, but done the other direction (transfering the shape or morphs from V3 to Antonia with the 3 different methods).
