Like the Generic Orifice, but an invisible cone that affects an orifice but has no other physics collisions. So fingers and various objects could deform an orifice. I had created "Dilator" to address this but I don't think it does a very good job and collisions occur with the character's invisible limbs.

It would be cone shaped to dilate from 0% to 100% so the creator could set the penetration depth to how much they want the dilation to be.
