    “Name Space” By default this will say “Person”. This will display the name of the currently selected Person Atom. You can rename it here as well.


    ”Soft Physics Enabled”

    Soft physics Enabled toggles on multiple colliders attached to the breast vertices. This gives a closer approximation to a natural deformation of the breasts when handled. The trade off is that it does take more processing power to simulate and should only be used when the effect is needed.


    ”Auto Fat Collider Radius” Automatically adjusts the Fat Collider Radius based on morphs that affect the size of the breast. This gif example demonstrates the effect breast morphs have on the Fat Colliders when this is toggled “On”.



    ”Fat Collider Radius” When ”Auto Fat Collider Radius” is toggled “off” you can freely adjust the size of the colliders attached to the vertices of the breasts. Allowing you to fine tune the amount of deformation that happens.



    ”Fat Back Force” Affects the amount of pressure on colliders affects the other colliders within the breast. As demonstrated within the below gifs, The lower amount ”Fat Back Force” is the less the upper part of the breast moves when pressed from below. When ”Fat Back Force” is higher the more the upper part of the breast is affected.




    ”Fat Collider Depth” Moves the fat colliders in or out of the breast along the local axis of the vertices that they are attached to.



    Fat Back Force Max Force” Limits the amount of force that is applied to the other colliders within the breast. Be aware that the higher this number is the more likely you will have a physics explosion. Adjust sparingly.

    ”Fat Spring” Adjusts how quickly the breast will spring back into shape after being handled. In the gifs below you can see that the lower the spring is the slower the breast falls back into place.



    ”Fat Back Force Threshold” Affects the solidity of the breast. The higher the number the more solid the breast appears to be. The lower the number the softer the breasts will appear. In essence it changes the amount of force that needs to be applied to affect the entire breast.



    ”Fat Damper” Limits the amount of secondary motion that happens across the breast. The lower the number the more bounce will happen. The higher the number the faster the motion will come to rest.



    ”Fat Distance Limit”




    ”Fat Mass” Increases the apparent weight of the fat in the breast. Giving it more force when interacting with objects of lesser mass or weight.


    ”Breast Hard Colliders” Are an alternative to soft physics interaction that has a lower impact on your cpu. They should be used anytime you want physics collision on the breasts that does not require subtle deformations of the skin. It’s a good practice to use either soft or hard colliders, not both at the same time.





    ”Breast Soft Physics Self Collide” Is a toggle that allows the soft physics of the breasts to collide with each other.






    The following physics sliders are used to adjust the physics settings of specific vertex areas around the breasts while Soft Physics are enabled. They do not have any effect on Hard Collider physics. Each area has a Spring Multiplier and a Damper Multiplier to control how the mesh deforms during physics based actions. “Spring” affects how the vertices act while in motion. While “Damper” affects how the vertices return to shape after movement. In the following picture examples I mark out the general vertices that make up the specific area being affected by the sliders. In the gif examples I’m pushing the sliders into extreme ranges to make the affected areas very clearly defined.

    The “Main” tissue of the breast is the large area between the “Areola” and the ”Outer” verts that connect with the chest bone.

    ”Main Damper Multiplier”




    The “Areola” area of the breast are the ring of vertices between the “Main” and “Nipple”

    ”Areola Spring Multiplier”

    ”Areola Damper Multiplier”




    The “Outer” area of the breast is directly connected to the chest vertices and bridge to the “main” vertices.

    ”Outer Spring Multiplier”

    ”Outer Damper Multiplier”




    The “Nipple” vertices are exactly where you would expect them to be.

    Much of this material is drawn from and inspired by this excellent article posted by Hub member MaF on their vamjapan website located here:

    It is a very interesting read with an approach to understanding the settings that is different from what I did here. They also go into detail regarding how using the different combinations of these settings can manifest a wide range of breast types.

    A few different plugins available on VaM hub directly related to breast settings.
