# Compute Deformation Node

## Description

This node lets you pass compute deformed vertex data to a vertex shader, and only works with the [Entities Graphics package](https://docs.unity3d.com/Packages/com.unity.entities.graphics@latest/). You must provide `DeformedVertexData` in the `_DeformedMeshData` buffer. The node uses the `_ComputeMeshIndex` property to calculate where the `DeformedVertexData` associated with the current mesh are located in the `_DeformedMeshData` buffer. To output data, you must either install both the Entities Graphics package and DOTS Animation packages, or use a custom solution.
