the shoes mashed during animation?

Postby makehuman987 » Mon Nov 15, 2021 9:58 am

Hi,
I used shoes in makehuman. When imported into blender, the feet penetrated through the shoes during animation, as the pic shows(shoe_2.jpg).
This penetration seems to happen during motion. When the character stayed still(see shoe_1.png), penetration didn't occur.
Is this due to the mismatching of solution on shoes and body during motion? How could this problem be solved?

Hi

For the shoes "hide faces under clothes" should be used. Same goes for the pants, skin bleeds through. So it should be exported without the skin under the clothes. The reason for bleeding through is simply mathematical:

http://www.makehumancommunity.org/wiki/Documentation:MakeClothes_Delete-Groups

The standard shoes should not bend like the foot. Afaik they are designed like that. So the sole is made stiff and it follows a few vertices of the foot (looks like the toe-box region). It also depends on the skeleton (game engine, default whatever) The animation (I guess) deforms the foot itself, which normally has a foot and at least one toe-bone.

So best to export with delete vertices or try some of the shoes from the user asset repository. They partly are able to deform in a way which might be wrong in reality but correct if you need the skin under the shoes, because not all are made the same way.

Btw.: Most closed heels are deleting the foot itself because it would peek through in front.

Thanks a lot, punkduck.
This really helps and makes a good explanation. Yes, it's reasonable not to devote great effort to making the shoes fit feet perfectly since shoes and feet are made separately.
Good advice, thanks again.
