建形修改器

建形 修改器使网格物体的面随着时间的推移一个接一个地出现或消失。

默认情况下，面按照它们存储在内存中的顺序显示 (默认为创建顺序)。可以通过 排列网格元素 调整面/顶点顺序。

选项

建形修改器。

Start Frame

创建过程的起始帧。

长度

对物体建形所用的帧数。

反向

修改器将反向运行，基本上会把它用作 "解构" 效果。 这对于使一组多个物体逐渐消失很有用。

随机

创建物体的面时，顺序随机化。

种子

随机种子。当 随机 勾选后，修改此值得到不同的 "随机" 顺序。 对于给定的种子/网格集，这个顺序总是相同的。

例子

The Build modifier can be used to make a large number of items to progressively appear, without resorting to animating the visibility of each one by one. Examples of this include a mesh containing vertices only, which is used as an Instancing Vertex emitter, and has the Build modifier on it. Such a setup is a workaround/technique for being able to art-direct a semi-random layout of a collection of objects (e.g. leaves/balls forming a carpet). This can be preferable to particles e.g. due to undesirable distribution of items leaving random gaps and overlapping in other places.
