Stretch, Elasticity and Tether Limit

The Stretch, Elasticity and Tether Limit decide the softness of a soft-cloth. The Stretch affects the entire soft cloth, the Elasticity focuses on the reflexive properties for the cloth, and the Tether Limit determines the level of stretching the soft cloth will exhibit.

Stretch

The Stretch determines how hard the cloth will be during collision. The higher the value, the harder the soft cloth is. The illustrations below show the status of two soft cloth props with different Stretch values.

Stretch = 0

Stretch = 100

Elasticity

The Elasticity setting is the level of stretching between two vertexes of a soft cloth. When this value is lower, there will be less stretching when one side of the vertex is subject to a physics force. Therefore, a lower value is more suitable for sturdy materials such as cotton or demin.

Elasticity = 1 (low bouncing ability)

The soft cloth looks as stiff as cotton.

Elasticity = 100 (high bouncing ability)

The soft cloth looks as elastic as lycra.

Tether Limit

The Tether Limit determines the anticipated final size of the soft cloth after it rests from any animations, such as moving or stretching.

Tether Limit = 1.00 (100%)
The soft-cloth keeps the size of 100% when it comes to a rest.

Tether Limit = 0.80 (80%)
The soft-cloth shrinks to size of 80% when it comes to a rest.

Tether Limit = 1.20 (120%)
The soft-cloth stretches to size of 200% when it comes to a rest.
