# 网面缓存修改器¶

The Mesh Cache Modifier is used so animated mesh data can be applied to a mesh and played back, deforming the mesh.

This works in a similar way to shape keys but is aimed at playing back external files and is often used for interchange between applications.

Note

## 选项¶

The input file format (currently .mdd and .pc2 are supported).

### Evaluation¶

This setting defaults to 'Overwrite' which will replace the vertex locations with those in the cache file. However, you may want to use shape keys, for example, and mix them with the mesh-cache. In this case you can select the 'Deform' option which integrates deformations with the mesh-cache result.

Note

This feature is limited to making smaller, isolated edits and will not work for larger changes such as re-posing limbs.

None or Linear which will blend between frames; use linear when the frames in the cache file do not match up exactly with the frames in the blend-file.

### Time Mapping¶

Evaluates the entire animation as a value from (0 - 1).

Property used for animation time, this gives more control of timing -- typically this value will be animated.

### Axis Mapping¶

The axis for forward and up used in the source file.

Tip

MDD 和 PC2 格式都依赖于网格上的顶点顺序保持不变，这个是受限于所用的方法，所以要小心不要在使用该修改器后添加或删除顶点。
