# 网格变形修改器¶

The Mesh Deform Modifier allows an arbitrary mesh (of any closed shape) to act as a deformation cage around another mesh.

## 选项¶

The Mesh Deform Modifier is reasonably easy to use but it can be very slow to do the calculations needed to properly map the deform mesh cage to the deformed object.

An optional vertex group of the object's mesh to restrict the vertices that will be affected by this modifier. Vertices not in this group will not be deformed.
Invert <->

Inverts the influence of the selected vertex group, meaning that the group now represents vertices that will not be deformed by the modifier.

(The setting reverses the weight values of the group).

The Precision number button controls the accuracy with which the deform mesh cage alters the deformed object, when the points on the cage are moved. Raising this value higher can greatly increase the time it takes the Mesh Deform Modifier to complete its binding calculations, but it will get more accurate cage mapping to the deformed object.

The setting is deactivated by default to save memory and processing time when binding. Like with Precision, this setting is unavailable once a cage has been bound.

Links the current vertex positions of both the modified geometry and the deformer Object chosen together. An unbound Mesh Deform Modifier has no effect -- it must be bound so that altering the shape of the deform mesh cage actually alters the shape of the modified object.

Warning

Depending on the settings of the Mesh Deform Modifier and complexity of the deform mesh cage and/or deformed object, it can take a long time for this operation to complete. This can result in Blender not responding to user's actions until it has completed.

To be safe, save your blend-file before proceeding!

The deformed object will, however, reset back to its original shape that it had before it was bound to the deform mesh cage.

Warning

Significant changes to the entire change mesh (such as rotating the cage upside down) can cause noticeable artifacts.

These can be reduced by binding with a higher Precision, however, it is a known limitation with this modifier and cannot be avoided entirely.

## 提示¶

• 保证笼网格上的法线指向外面，它们用来决定笼子的里与外。
• 除了最外面的笼子，笼子（松散的或构成其他较小的笼子）里更多的的面可以用作额外的控制。小笼也可以与大笼重叠，例如，为了获取眼部额外的控制，两个小球构成的笼可以加载它们周围。
