Mesh Cache(メッシュキャッシュ)モディファイアー¶
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.
重要
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.

Mesh Cache(メッシュキャッシュ)モディファイアー。¶
- Format(フォーマット)
Specifies the input file format. The modifier currently supports
.mdd
and.pc2
.- File Path(ファイルパス)
Path to the external cache file containing the animation data.
- Influence(影響)
Controls the strength of the deformation. Lower values blend the cached animation with the original mesh shape.
- Deform Mode(変形モード)
Determines how the cache data influences the mesh:
- Overwrite:
Replaces vertex positions with those from the cache file.
- Integrate:
Blends the cache deformation with existing deformations, such as shape keys or modifiers.
注釈
This mode is best suited for minor, localized adjustments. Large transformations, such as reposing limbs, may not work as expected.
- Interpolation(補間)
Controls how frames between cache data are handled:
- None(なし):
Uses only the raw frame data from the cache without interpolation.
- Linear(リニア):
Blends between frames for smoother transitions, useful when cache frames do not align perfectly with the scene frames.
- Vertex Group(頂点グループ)
設定されている場合、その頂点グループ内の頂点のみにエフェクトを制限します。
- Invert(反転)
<->
選択した頂点グループの影響を反転します。つまり、反転するとグループは、モディファイアーによって変形されない頂点を表します。
この設定は、グループのウェイト値を逆にします。
- Invert(反転)
Time Remapping¶
- Time Mode(タイムモード)
Defines how animation time is interpreted:
- Frame(フレーム):
Ignores timing data from the cache and plays back frames directly. This mode provides direct control over playback speed.
- Time(時間):
Uses the cache's timing data, including offsets and frame durations.
- Factor(係数):
Maps the entire animation to a range between
0
and1
for precise control.
- Play Mode(再生モード)
Specifies how playback timing is determined:
- Scene(シーン):
Uses the scene's current frame for playback.
- Frame Start(開始フレーム)
Defines the starting frame for playback.
- Frame Scale(フレームスケール)
Adjusts the playback speed by scaling time.
- Custom(カスタム):
Allows manual control of animation timing.
- Evaluation Value(評価フレーム)
Determines animation playback position, which can be animated for precise control.
Axis Mapping¶
- Forward/Up Axis(前方/上向きの軸)
Specifies the forward and up axes of the imported animation, ensuring proper orientation.
- Flip Axis(座標軸の反転)
Flips the animation along a chosen axis if the imported data requires correction.
