Can we straighten a distortion of a cloth after wore by a character?

James

1. After I made a head cover and put it on a character. On certain area the shape change a bit following the shape of the face.
Creating a distortion.

Is it unevitable? How to solve this distortion?

2. When simulated
The area under the chin gets elongated.
I need it to stick to the chin.
I tried to eliminiate the weight of dforce weighmap on that area, but if the neck turned, that part under the chin get left behind when simulated.
So what can I do?

3. How to add thickness?

Ideally there should be more thickness for the whole cloth. And The yellow part needs to be thicker than the rest.

1. Is this from morphing or posing? If it's morphing then really you need a custom morph to match the figure morph.

2. Didn't you ask this before? It looks to be the simulation taking up the slack, if there is much more space than is needed for the minimum offset then the model will close up that space as it simulates and the result will be that it can hang lower.

3. Didn't you ask this before too? Modelled thinckness you can't fully, but you can turn the edge to make it look thick and use a dForce addon to hold it in place - Mada has posted a link to her video on this several times in various threads. If you want the fabric to behave as if it was stiffer then it's a mixture of adjusting the surface settings (and possibly the simulation settings as a stiffer surface may well need longer to settle and more iterations to diffuse the energy) and mesh resolution (a sparser mesh will seem thicker).

For the question number 2:
Sooo... are you suggesting to make the cloth geometries smaller, as close as possible to the skin?

Didn't you ask this before?
Well, similar but not the same.
The previous one, I have trouble with  a dress that becomes very springy, and draped too much. No matter how I changed it to a more stiffer surface (or maybe I dial wrong parameters). I changed also the density and the gravity.
At the end I solved it by accident, by reducing the number of geometries.
Resulting a very less springy cloth and draped exactly as I wanted.

This one is not springy, but I dont want to make it stiffer, cos the whole surface will looks less natural as a silk.
I was hoping, maybe there were solutions I didn't know of, like how to stick certain area to the chin, like in MD with its Tack.
Or maybe there's a way to make one part of area more silky, and another part more stiffer.

For the question number 3:
Didn't you ask this before too?
Hemm... I dont remember. It really blank in my head, right now..
Probably if I did, I didn't yet grasp the answers.
Sometimes I need several knowledge more to understand some answers.
Like your no.3 answer.
All I get that Mada have a clue, something to do with Dforce add on, something to do wtih make stiffer surface, and the rest I don't know yet the connection.
So what I'm going to do next is find Mada's video. Then maybe I can connect all the dots.

this is the dforce add on tutorial :)

For the problem you have under the chin - when you remove the influence weightmap for dforce you're basically painting it back to full conforming outfit. For it to work properly in that case you need to smooth the rigging weightmap for the neck areas, as well as fix the JCMs for when you twist the head and neck. When you simulate dforce will ignore areas that's been painted out, and whatever you have there is from how well you rigged it.
