Interesting. What kind of potential do you think can be unlocked with this tool? Could it potentially allows for gradually pulling down/pushing up the cups of the bra covering the breasts, for example? Or even pulling down / up of the panties?
I don’t think so; at the moment, the clipping occurs along a curved trajectory.
You could use this plugin as a foundation to write a similar script for this task.
However, I don’t see much point in that—it’s better to "hide" parts of the clothing using an alpha map or by assigning a separate material.
