Having properly weighted map will help a lot but the trick is that this properly weighted map in G2F that some people might praise so much for its gender-specificness isn’t actually gender specific weightmap, it is unisex. It appears as gender-specific because default shape sculpt is a female but this is smoke and mirrors. By transferring Genesis male morphs/shape sculpts back and forth (only main morphs, not JCMs) I get a male who is very much the same male I had in Genesis (with all JCMs), bends being better and all thanks to _generic_ improved weightmaps G2F has, but still very much and very noticeably male without an influence of supposed ‘female’ rigging.
There is nothing in G2F’s rigging that is gender-specific so the idea that female figure somehow has better “female” rigging is not true. General rigging improvement? - yes. Gender-specific rigging improvement? - no and G2F with the same rigging it has now could have been as easily made with default unisex sculpt shape, and two sets of morphs in areas where fat distribution is different.
Male-M3dia made a good point about topology. Look at my posts above. The weight map is only one part of the equation. You also need the correct mesh topology. From my example, you can see the V5 shape altered the crease point. So it was the shape that’s causing the issue. Putting in correction to the shape so the topology works better with the bending is the solution.
First of all, in your pictures I don’t see the need for correction. As human body can be very different, I don’t personally believe in ‘ideal’ bends and shapes - my own knees don’t bend exactly like corrected knees in your pictures and thus even corrected bends look no less (un)realistic personally to me than uncorrected ones.
But lets imagine that any drastic shape needs to have better, corrected bends. Why do you think you will avoid doing this with G2F? If tech behind the rigging didn’t change, any drastic shape in G2F will require corrections to make better bends, - and considering that the difference between default Genesis shape and V5 is a smaller difference than the difference between G2F and its own Heavy morph, meshflow-wise, you’ll have to do no fewer corrections than in Genesis. Just having gender-specific initial figure won’t eliminate the need in corrections or lessen their amount when mesh is altered so much as in Heavy morph or you need a such precision like in your V5 example.
In case if tech is improved up to point that rigging and weightmaps autoadjusts itself to meshflow (I don’t think we are there yet), again, the Genesis 2 should have been unisex figure, because the difference between male and female shapes isn’t all that drastic as the difference between G2F and its own Heavy morph, so technically if this technology exist than nothing would prevent Genesis 2 from being unisex in this case.
So what the point of default female shape again? You either do corrections for any change of shape anyway with current level of technology, or unisex figure would have autocorrected bends if technology is improved that much, or, in case if G2F rigging is so good right now it doesn’t need JCMs to correct bends on Heavy morph (which doesn’t have any joint corrections last time I’ve checked), you can use it on unisex shape as it is because the difference in meshflow between unisex and G2F shape is a smaller difference than meshflow difference between G2F shape and Heavy G2F shape.
Also look at those pictures.
First is a default female G2F shape bend, posed like on your pictures. When compared its underknee bend crease to your corrected V5 bend crease (from post #507), it doesn’t look the same and it looks more like a bend from post #506, which I presume wasn’t corrected as much.
Second picture is same G2F with OriginalGenesis shape (unisex one) unlocked, and from what I see the underknee bend is closer on it to V5 bend you did with D-Formers in #507, which I presume is more correct from your point of view.
So why default G2F underknee ‘gender-specific’ bend considered to be better than original Genesis bend and not to be corrected? From what I see from pictures you posted, you will have to correct G2F default bends anyway if V5 underknee bend crease from post #507 is of any indication of better bends you want to have, because it isn’t any near this sharper shape.
G2F still has a lot of hidden correction stuff, only they aren’t JCMs as much as CTRL properties (basically, scaling and pushing).
