public void SetViewMatrix (Matrix4x4 view);


viewView (world to camera space) matrix.


Add a command to set the view matrix.

View matrix is the matrix that transforms from world space into camera space.

When setting both view and projection matrices, it is more efficient to use SetViewProjectionMatrices.

Note: The camera space in Unity matches OpenGL convention, so the negative z-axis is the camera's forward. This is different from usual Unity convention, where the camera's forward is the positive z-axis. If you are manually creating the view matrix, for example with an inverse of Matrix4x4.LookAt, you need to scale it by -1 along the z-axis to get a proper view matrix.

using UnityEngine;
using UnityEngine.Rendering;

// Attach this script to a Camera and pick a mesh to render. // When you enter Play mode, a command buffer renders a green mesh at // origin position. [RequireComponent(typeof(Camera))] public class ExampleScript : MonoBehaviour { public Mesh mesh;

void Start() { var material = new Material(Shader.Find("Hidden/Internal-Colored")); material.SetColor("_Color",;

var tr = transform; var camera = GetComponent<Camera>();

// Code below does the same as what camera.worldToCameraMatrix would do. Doing // it "manually" here to illustrate how a view matrix is constructed. // // Matrix that looks from camera's position, along the forward axis. var lookMatrix = Matrix4x4.LookAt(tr.position, tr.position + tr.forward, tr.up); // Matrix that mirrors along Z axis, to match the camera space convention. var scaleMatrix = Matrix4x4.TRS(, Quaternion.identity, new Vector3(1, 1, -1)); // Final view matrix is inverse of the LookAt matrix, and then mirrored along Z. var viewMatrix = scaleMatrix * lookMatrix.inverse;

var buffer = new CommandBuffer(); buffer.SetViewMatrix(viewMatrix); buffer.SetProjectionMatrix(camera.projectionMatrix); buffer.DrawMesh(mesh, Matrix4x4.identity, material);

camera.AddCommandBuffer(CameraEvent.BeforeSkybox, buffer); } }
