Description

A block of material values to apply.

MaterialPropertyBlock is used by Graphics.DrawMesh and Renderer.SetPropertyBlock. Use it in situations where you want to draw multiple objects with the same material, but slightly different properties. For example, if you want to slightly change the color of each mesh drawn. Changing the render state is not supported.

Unity's terrain engine uses MaterialPropertyBlock to draw trees; all of them use the same material, but each tree has different color, scale & wind factor.

The block passed to Graphics.DrawMesh or Renderer.SetPropertyBlock is copied, so the most efficient way of using it is to create one block and reuse it for all DrawMesh calls. Use SetFloat, SetVector, SetColor, SetMatrix, SetTexture, SetBuffer to add or replace values.
