nCloth Pressure attributes

Pressure

Pressure Method

Specifies how the Pressure value for the current nCloth object is defined.

The manual setting defines pressure as a simple user input value that can be keyframed. The volume tracking model computes the pressure based on the current volume of the cloth combined with inflow and outflow of air.

Manual Pressure Setting

Pressure is defined as a user-defined value that can be keyframed.

Volume Tracking Model

Pressure is defined as a solver-computed dynamic value that is based on the current volume of the nCloth combined with the inflow and outflow of air. Note that higher Air Density values (and thus iterations) make the internal air more incompressible when using the Volume Tracking Model.

Pressure

Specifies a force applied along the surface normal direction of the current nCloth object when the Pressure Method is set to Manual.

Pressure is only available when Manual Pressure Setting is the current Pressure Method.

Pressure Damping

Specifies the amount the air pressure is damped for the current nCloth object.

Start Pressure

Specifies the relative air pressure inside the current nCloth object at the start frame of its simulation.

Start Pressure is only available when Volume Tracking Model is the current Pressure Method.

Pump Rate

Specifies the rate at which air pressure is added to the current nCloth object.

Pump Rate is only available when Volume Tracking Model is the current Pressure Method.

Air Tightness

Specifies the rate at which air can escape from the current nCloth object, or how permeable its surface is.

Air Tightness is only available when Volume Tracking Model is the current Pressure Method.

Incompressibility

Specifies the incompressibility of the current nCloth object’s internal air volume. This also affects the amount of force applied when air is pumped into the nCloth. Note that a higher Incompressibility value may require more solver calculation time.

Incompressibility is only available when Volume Tracking Model is the current Pressure Method.

Seal Holes

When on, the physical holes in the current nCloth object are treated as being capped or sealed. If holes are not sealed, air can escape from them.
