# MaterialPropertyBlock > A block of material values to apply. ## Definition * **Type:** Class * **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md) * **Assembly:** UnityEngine.CoreModule ```csharp public sealed class MaterialPropertyBlock ``` ## Remarks MaterialPropertyBlock is used by [Graphics.RenderMesh](/engine/6000.7/script-reference/unityengine/graphics/rendermesh.md) and [Renderer.SetPropertyBlock](/engine/6000.7/script-reference/unityengine/renderer/setpropertyblock.md). 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.RenderMesh](/engine/6000.7/script-reference/unityengine/graphics/rendermesh.md) or [Renderer.SetPropertyBlock](/engine/6000.7/script-reference/unityengine/renderer/setpropertyblock.md) is copied, so the most efficient way of using it is to create one block and reuse it for all DrawMesh calls. Use [MaterialPropertyBlock.SetFloat](/engine/6000.7/script-reference/unityengine/materialpropertyblock/setfloat.md), [MaterialPropertyBlock.SetVector](/engine/6000.7/script-reference/unityengine/materialpropertyblock/setvector.md), [MaterialPropertyBlock.SetColor](/engine/6000.7/script-reference/unityengine/materialpropertyblock/setcolor.md), [MaterialPropertyBlock.SetMatrix](/engine/6000.7/script-reference/unityengine/materialpropertyblock/setmatrix.md), [MaterialPropertyBlock.SetTexture](/engine/6000.7/script-reference/unityengine/materialpropertyblock/settexture.md), [MaterialPropertyBlock.SetBuffer](/engine/6000.7/script-reference/unityengine/materialpropertyblock/setbuffer.md) to add or replace values. Note that this is not compatible with [SRP Batcher](/engine/6000.7/manual/analysis/graphics-performance-profiling/in-urp/reduce-draw-calls-urp/srpbatcher/srpbatcher.md). 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. The following example creates 10 GameObjects with random colors using `MaterialPropertyBlock`. To use the example, attach a prefab to the `myPrefab` property.
