This is a question pertaining to Millenium 3 figures such as Victoria 3.

I am told that as a general rule, the grandparent actor cannot follow a grandchild. In other words, in Hip > Buttock > Thigh, the hip cannot follow the thigh. However, in some vendors' clothing models here on Renderosity, they have been able to get the hip to follow the thigh. The significance of this is that if you conform a dress to Victoria 3, simply moving her thigh will also deform the hip, which will follow the thigh (its grandchild).

Does anyone know how the rule is defied? Is there a certain procedure?
