MaterialPropertyBlock

class in UnityEngine

切换到手册

描述

要应用的材质值代码块。

MaterialPropertyBlock 由 Graphics.DrawMeshRenderer.SetPropertyBlock 使用。在 希望绘制具有相同材质,但属性 略有不同的多个对象时可使用它。例如,如果 要稍微更改绘制的每个网格的颜色。不支持更改渲染状态。

Unity 的地形引擎使用 MaterialPropertyBlock 绘制树;它们全都使用 相同材质,但是每棵树具有不同的颜色、缩放和风力系数。

传递给 Graphics.DrawMeshRenderer.SetPropertyBlock 的代码块将被复制,因此使用它的最高效方式是 创建一个代码块并将它重复用于所有 DrawMesh 调用。使用 SetFloatSetVectorSetColorSetMatrixSetTextureSetBuffer 可添加或替换值。

Note that this is not compatible with [wiki:SRPBatcher|SRP Batcher]]. Using this in the Universal Render Pipeline (URP), High Definition Render Pipeline (HDRP) or a custom render pipeline based on the Scriptable Render Pipeline (SRP) will likely result in a drop in performance.
