Converts a Vector4 to a Vector3.

A Vector4 can be implicitly converted to a Vector3. (w is discarded).

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Start() { // Shader vectors are always Vector4s. // But the value here is converted to a Vector3. Vector3 value = Vector3.one; Renderer renderer = GetComponent<Renderer>(); renderer.material.SetVector("_SomeVariable", value); } }
