编号
编号 节点给出一个整数值,表示列表中每个元素的位置,从零开始。这取决于几何体中数据的内部顺序,这在 3D 视口中不一定可见。但是,编号值在电子表格编辑器的最左列中可见。
Note
Indices in geometry data are often defined by the internals of complex algorithms that create it. If no inputs change, indices will be the same when the same node tree is executed multiple times. However, they may not be predictable when inputs to nodes that generate geometry or change its topology are adjusted. Additionally, updates to algorithms in newer versions of Blender may change the order of generated elements.
为了避免依赖于一致性指数,建议在本地计算它们,或者避免在它们必须一致时更改拓扑结构的操作。
