The aspect ratio of the projection.
This is projection width divided by height. An aspect ratio of 1.0 makes the projection square; a ratio of 2.0 makes it twice as wide than high. Additional resources: projector component.
using UnityEngine;
public class Example : MonoBehaviour { void Start() { // Get the projector Projector proj = GetComponent<Projector>(); // Use it proj.aspectRatio = 2.0f; } }
