网格缓存修改器

The Mesh Cache modifier applies animated mesh data from an external file to a mesh, allowing it to deform over time. It is commonly used for importing animations from other applications, enabling smooth playback of cached deformations.

This modifier functions similarly to shape keys, but is specifically designed for playback of externally stored animations rather than keyframe-based deformations.

Important

Both .mdd and .pc2 file formats rely on a consistent vertex order throughout the animation. Adding, removing, or reordering vertices after this modifier may cause unintended results.

网格缓存修改器。

格式

Specifies the input file format. The modifier currently supports .mdd and .pc2.

文件路径

Path to the external cache file containing the animation data.

影响

Controls the strength of the deformation. Lower values blend the cached animation with the original mesh shape.

形变模式

Determines how the cache data influences the mesh:

覆盖:

Replaces vertex positions with those from the cache file.

Integrate:

Blends the cache deformation with existing deformations, such as shape keys or modifiers.

Note

This mode is best suited for minor, localized adjustments. Large transformations, such as reposing limbs, may not work as expected.

插值

Controls how frames between cache data are handled:

:

Uses only the raw frame data from the cache without interpolation.

线性:

Blends between frames for smoother transitions, useful when cache frames do not align perfectly with the scene frames.

顶点组

如果设置了顶点组,则将效果限制在该顶点组中的顶点。

反转 <->

反转所选顶点组的影响,这意味着该组现在表示不会被修改器改变形状的顶点。

反转顶点组的权重值。

时间重映射

时间模式

Defines how animation time is interpreted:

帧/框:

Ignores timing data from the cache and plays back frames directly. This mode provides direct control over playback speed.

时间:

Uses the cache's timing data, including offsets and frame durations.

系数:

Maps the entire animation to a range between 0 and 1 for precise control.

播放模式

Specifies how playback timing is determined:

场景:

Uses the scene's current frame for playback.

起始帧

Defines the starting frame for playback.

帧缩放

Adjusts the playback speed by scaling time.

自定义:

Allows manual control of animation timing.

估算时刻

Determines animation playback position, which can be animated for precise control.

轴向映射

向前/向上轴

Specifies the forward and up axes of the imported animation, ensuring proper orientation.

翻转轴向

Flips the animation along a chosen axis if the imported data requires correction.
