CloseThe intended target usage of the Mesh GPU vertex buffer.
By default, Mesh vertex buffers have GraphicsBuffer.Target.Vertex usage target. If you want to access the mesh vertex buffer from a compute shader, additional targets need to be requested, for example GraphicsBuffer.Target.Raw.
using UnityEngine;
public class ExampleScript : MonoBehaviour { public Mesh mesh; public ComputeShader computeShader; void Start() { // Mark the vertex buffer as needing "Raw" // (ByteAddressBuffer, RWByteAddressBuffer in HLSL shaders) // access. mesh.vertexBufferTarget |= GraphicsBuffer.Target.Raw; // Get the vertex buffer of the Mesh, and set it up // as a buffer parameter to a compute shader. var vertexBuffer = mesh.GetVertexBuffer(0); computeShader.SetBuffer(0, "MeshVertexBuffer", vertexBuffer); vertexBuffer.Dispose(); } }
