## Remarks

A metadata value is a uint32 value tied to a DOTS-instanced property. Unity passes this metadata to the shader.

| [NameID](/engine/6000.6/script-reference/unityengine/rendering/metadatavalue/nameid.md) | The name ID of the property that the metadata value is tied to. To specify a value for a property declared with UNITY\_DOTS\_INSTANCED\_PROP(float4, Example), pass Shader.PropertyToID("Example") here. |
| [Value](/engine/6000.6/script-reference/unityengine/rendering/metadatavalue/value.md)   | Unity passes this uint32 value to the shader for this property. The value is shared between all instances in the batch. Usage example: provide a buffer address for the property.                        |
