Lift and Drag (New for 5)

The Lift and Drag settings are effective with singular surfaces; and they only take obvious effect when the surface moves.


Lift is produced by changing the direction of the fluid flow (air, water) around a moving soft body. It is produced because the air below the soft body is generally at a higher pressure than the surrounding atmospheric pressure, this happens as the air above the soft body is generally at a lower atmospheric pressure. Please note that the Lift force will always react to the opposite direction of Gravity. Collaborating with gravity, Lift not only creates a raising force but also ruffles up a soft body.

The lifting (L) and gravity (G) directions.

Lift = 200

Ruffles generated.


The component of force parallel to the oncoming flow is called Drag. It will then affect the direction of the Lift, and even pull the soft body towards the opposite direction of the initial move.

The moving (M) and dragging (D) directions.

Drag = 3000

The soft body is extended and no ruffles are produced

You may then mix-up these two settings to produce a turbulent and extended soft body.

Lift = 200

Drag = 3000
