Graphics.DrawMeshNow

Parameters

Description

Draw a mesh immediately.

This function will draw a given mesh immediately. Currently set shader and material (see Material.SetPass) will be used.

The mesh will be just drawn once, it won't be per-pixel lit and will not cast or receive real-time shadows. If you want full integration with lighting and shadowing, use Graphics.DrawMesh instead.

using UnityEngine;
using System.Collections;

// Attach this script to a Camera
public class ExampleClass : MonoBehaviour {
    public Mesh mesh;
    public Material mat;
    public void OnPostRender() {
        // set first shader pass of the material
        mat.SetPass(0);
        // draw mesh at the origin
        Graphics.DrawMeshNow(mesh, Vector3.zero, Quaternion.identity);
    }
}
