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.
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.

| HasBuffer | Checks if MaterialPropertyBlock has the ComputeBuffer property with the given name or name ID. To set the property, use SetBuffer. |
| HasColor | Checks if MaterialPropertyBlock has the Color property with the given name or name ID. To set the property, use SetColor. |
| HasConstantBuffer | Checks if MaterialPropertyBlock has the ConstantBuffer property with the given name or name ID. To set the property, use SetConstantBuffer. |
| HasFloat | Checks if MaterialPropertyBlock has the Float property with the given name or name ID. To set the property, use SetFloat. |

| HasInteger | Checks if MaterialPropertyBlock has the Integer property with the given name or name ID. To set the property, use SetInteger. |
| HasMatrix | Checks if MaterialPropertyBlock has the Matrix property with the given name or name ID. This also works with the Matrix Array property. To set the property, use SetMatrix. |
| HasProperty | Checks if MaterialPropertyBlock has the property with the given name or name ID. To set the property, use one of the Set methods for MaterialPropertyBlock. |
| HasTexture | Checks if MaterialPropertyBlock has the Texture property with the given name or name ID. To set the property, use SetTexture. |
