Internal Springs¶
As stated in the introduction, cloth physics are simulated through Springs connecting vertices on the surface of a mesh. But these springs only interact on the surface and only apply to 2D surfaces. 3D or Internal Springs can be used to make a mesh behave similarly to a Soft Body. Internal springs can be enabled by toggling the checkbox in the Internal Springs panel header.
- Max Spring Creation Length
The maximum length an internal spring can have during creation. If the distance between internal points is greater than this, no internal spring will be created between these points. A length of zero means that there is no length limit.
- Max Creation Diversion
The maximum angle that is allowed to use to connect the internal points can diverge from the vertex normal.
- Check Surface Normals
Requires the points the internal springs connect to have opposite normal directions.
- 张力
材料抗拉强度.
- 压缩

- Vertex Group
The Tension and Compression of internal springs can be controlled via a Vertex Group to specify which the portions of the mesh have internal springs or the spring strength.
- Max Tension
Maximum tension stiffness value.
- Max Compression
Maximum Compression stiffness value.
Pressure¶
Cloth pressure allows the simulation of soft-shelled objects such as balloons or balls that are filled with some sort of fluid. This fluid can be seen either as a gas or a liquid however, both are generalized as "fluids". Cloth pressure can be enabled by toggling the checkbox in the Pressure panel header.
Note
Non-manifold meshes will work with cloth pressure however, pressure will escape out of the mesh holes and cause drifting or propulsion forces. One way to get around this is by using the Vertex Group to exclude the non-manifold portions of the mesh.
- Pressure
The uniform pressure that is constantly applied to the mesh. This value can be negative to simulate implosions or any other case where an object has outside pressure pushing inwards.
- Custom Volume
Use the Target Volume parameter as the initial volume for the cloth. This avoids having to use the Pressure to first inflate the object.
- Target Volume
The mesh volume where the inner/outer pressure will be the same. If set to zero the volume will not contribute to the total pressure.
- Factor
Scalar control over the overall pressure.
- Vertex Group
Cloth pressure can be controlled via a Vertex Group to specify which the portions of the mesh to apply pressure. Zero weight means no pressure while a weight of one means full pressure.
Note, faces with a vertex that has zero weight will be excluded from the Target Volume calculation.
