I just tried it, and the face template was blank except for the eye controls. Though I seem to recall some talk about having to delete the DIM version and manually install it or something, so maybe I have a bad install.
I already know how to do facial expressions by hand. I want to learn the rigid, scientific method to expand my skillset and use both appropriately.
Ah, this looks like exactly what I'm trying to find. And it's got glowing reviews on Amazon.
I'll probably pick this one up, thanks!
Learning by trial and error has been around for several millenia. Living in the age of PHS has made many people lazy and somewhat dimwitted on how to do things. Did you know having a high IQ does not mean someone is smart, it only means someone read something and, thanks to memory, when questioned about it they got the answer right. Still doesn't make them smart.
I know lots of big words, their meaning and how to use them, also have an IQ of 170. Do you know how I make clothes (as in real life and applied to Drawing and 3D), I go shopping and happen to see an article of clothing in a store. I like it so much I go home and make it that day...no pattern, no book, no instruction. I just know how it's made and do it.
Knowing the AUs doesn't help you map to the DAZ facial rig. The rig controls the G8 facial bones and blendshapes that make the final expression. The rig is *based* on FACS meaning it mimics the facial groupings identified by the system (so scrunching a brow with the new rig in principle looks better than in the old rig). The rig is not a reconstruction of the AUs (i.e. the rig UI elements do not directly correspond to AU 1/2/3/etc) nor should it be. The end user doesn't need to know that the rig is based on FACS to know how to work with it. It's literally a framework the rig is based on -- and also a buzzword that marketing loves to run with. You the artist just are supposed to notice a better result. I'm sorry for repeating so much but no one in this thread is actually acknowledging that new DAZ facial rig != FACS AUs
This is like if Daz replaced the solver in the backend of dForce engine while slightly modifying the UI parameters. You wouldn't need to learn the new spring constant equations to know that dForce results look better.
I actually agree with the original poster, if FACS is a universal system used by professionals, there ought to be more specific examples of it's parameters in use, especially since they're actually number-coded as that earlier example showed. What we got here is basically Powerpose 2.0 and an explanation that all of the dials you need to make any expression are included - but not *how* to, that's for us to figure out.
I like the system and have no problems with the product, but I do think it's odd that there isn't a list floating around somewhere that gives precise values, like the IOR ones that we've come across that give exact numbers for 3D artists to use.
Hmm, alright. I understand what you're saying, but I still want to research FACS in more detail, so that I can decide for myself how well it correlates to the new facial rig. But thank you for the explanation.
It is up to the individual facial rig to set up the collective facial movements to follow FACS. It provides parameters so that the coder/rigger can set up their rig, not so that the end user deals with it.
This may be of interest to you to understand how it's used in production: https://adamspring.co.uk/2018/10/25/single-camera-facs-scanning-photogrammetry/
TLDR: Photoscans of an actors face in specific poses are taken and parts of the expressions are isolated and made into blendshapes that the rigger uses to create their rig. A choice is made ahead of time how many expressions/blendshapes will be included (there are tons and it isn't feasible to do all of them, rather you do them in groups). In the end you get something very high quality that works well for the use case of the animator.
An expression is a facial pose so apply your same logic to the body. You're literally asking for Daz to provide to you a step-by-step guide on how to achieve every possible human movement and pose.
To put it in perspective, with 80+ FACS controls you can have 6400 combinations. Add the various degrees of intensity for each control and you have numbers so large you need a special nomenclature for.
and then there is the gurning competition ...
I agree with th OP & Snow Sultan. The manual to use FACS is as important as FACS itself. It's the same deficit they have in DAZ Land with DAZ Studio and every other addon & preset are often incomplete such that you have to guess what clicking them does too.
