It’s pretty straight-forward question, but basically I’m wondering which one of these methods would be least demanding on the hardware and which one of these would look better for such a thing.
Thinking about using perlin noise and updating the mesh/terrain constantly.
In 3D?
Use a plane, add a colour, and then add the following script to it:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Ocean : MonoBehaviour
{
public Renderer water;
void Update ()
{
water.material.mainTextureOffset = new Vector2 (0, Time.time / 100);
water.material.SetTextureOffset ("_DetailAlbedoMap", new Vector2 (0, Time.time / 80));
}
}
