JavaScript => public var realtimeLightmapScaleOffset: Vector4;
C# => public Vector4realtimeLightmapScaleOffset;

Description 描述

The UV scale & offset used for a realtime lightmap.
用于实时光照的UV的缩放和偏移量。

Same as lightmapScaleOffset, but for realtime lightmaps.
与lightmapScaleOffset一样，除了实时光照图。

A realtime lightmap is a texture atlas and multiple Renderers can use different portions of the same lightmap.
一个场景可以储存多个光照贴图，并且渲染器可以使用这些光照贴图其中之一。这使得有可能在多个物体使用相同的材质，虽然每个物体可以引用不同的光照贴图或同一光照的不同部分。

The vector's x and y refer to UV scale, while z and w refer to UV offset.
该向量的x和y代表UV缩放，z和w代表UV的偏移。
