JavaScript => public var additionalVertexStreams: Mesh;
C# => public Mesh additionalVertexStreams;

Description 描述

Vertex attributes in this mesh will override or add attributes of the primary mesh in the MeshRenderer.

此网格中的顶点属性将重写或在 MeshRenderer 中添加属性的主网格。

This is used for the UVs for realtime lightmaps, but could also be used for vertex painting tools, etc.

该属性用于UVs 的实时灯光贴图，但是可能也用于顶点绘画工具，等。

For example, if the primary mesh doesn't contain the Mesh.colors channel, the colors from additionalVertexStreams are used. If the primary mesh contains the colors channel and the additionalVertexStreams mesh also has colors, then colors from additionalVertexStreams are used.

例如，如果主网格不包含Mesh.colors通道，该颜色从additionalVertexStreams 被使用。如果主网格包含颜色通道并且additionalVertexStreams 网格也有颜色，那么additionalVertexStreams 颜色被使用。
