Masking an area with the weight map tool does keep the bits you dont want to slide down the figure while allowing the rest to drape. However there is a bit of "but" here - the masked surfaces keep their position in space where what I think should happen is that they keep their position in space relative to the figure being dressed.
The attached is a simple test, genesis bent back and slightly twisted at chest level with a raised leg. THe masked portion of the dress is in exactly the same position as the zeroed pose while the rest drapes quite nicely.
Has anyone else noticed this / found a solution / am i doing something stupid?
Thanks
