复制变换约束¶
The Copy Transforms constraint forces an object or bone to match the location, rotation, and scale of a target.
选项¶
复制变换约束。¶
- 目标
The object or bone whose transforms to copy.
- 删除目标切变
在混合前移除目标变换中的切变，确保其仅包含平移、旋转和缩放。
If a child bone is rotated and its parent is non-uniformly scaled, it will get sheared, and so will any object that copies its transformation (middle cube). Use Remove Target Shear to fix this (right cube).¶
- 混合
Specifies how the target's current transformation (from all its constraints) is combined with the owner's original transformation (from its preceding constraints).
- 替换:
The target's transformation replaces the owner's.
- 初始前（完整）:
The target's transformation is applied before the owner's. The result is the same as the owner's transformation if it were a child of the target and there was no constraint.
If the "parent" is non-uniformly scaled and the "child" was originally rotated, the constraint will cause shearing, just like the default Inherit Scale Full setting for bones.
- 初始前（对齐）:
Prevents shearing by scaling the "child" along its own axes instead of the axes of the "parent," just like the Inherit Scale Aligned setting for bones.
- 初始前（拆分通道）:
Calculates each transform "channel" -- location, rotation, and scale -- separately from the others. This is the same as having a Copy Location constraint, a Copy Rotation constraint, and a Copy Scale constraint (all using Offset/Before Original). The result may be slightly different with sheared inputs, however.
The difference with Before Original (Aligned) is that the child's location is only affected by the parent's location, not by its rotation and scale.
- 初始后（完整/对齐/拆分通道）:
Like Before Original, except the result is the transformation of the target if it were a child of the owner.
没有约束。¶
With Before Original (Full), the cone is scaled along the cube's Y axis, causing shearing.¶
With Before Original (Aligned), the cone is scaled along its own Y axis, preventing shearing.¶
With Before Original (Split Channels), the cone's location is independent of the cube's rotation and scale.¶
- 目标/主体
The spaces for retrieving the transforms from the target and for applying them to the owner.
- 影响
How strongly the constraint affects the owner.
