Adjusting terrain texture tiling.

Archived Forums Questions & Answers

I have one terrain object in my game and I have "stages" which zooms the camera out. Now, what i want is to adjust the tiling of textures on my terrain, when the camera zooms out to a new "stage".

Is it possible to adjust the tiling at runtime?

Cheers.

It should be possible by setting the texture scale for the terrain shaders. I will try it later and answer your question.

@Bablo: Biggest issue is: Is your Terrain a custom terrain or is it the unity Terrain class?

It is a normal unity terrain. What do you mean by custom terrain? Like a custom 3d-model?

Ok, this is a try. I'm not writing this fully for you, but you could try something like this:

  • Add an extra `MonoBehaviour` class to your terrain gameobject
  • in the `Update()` method, get the renderer from the terrain component (see example)
  • foreach `Material`: `mat.SetTextureScale("name: like _Scale probably?", new Vector2(someFormula));`
  • You can get the main camera with: `Camera.main;`

Example, not tested and more like pseudo-code:

public class NewBehaviourScript : MonoBehaviour 
{
    // Use this for initialization
    void Start () {}

    // Update is called once per frame
    void Update () {

        // get the materials from the terrain
        Material [] ms = this.gameObject.GetComponent<Terrain>().renderer.materials;
        Camera main = Camera.main; // get the main camera

        // set texture scale each frame, 
        //because the camera will probably change each frame
        foreach (Material m in ms)
        {
            m.SetTextureScale("...", new Vector2(someFormula));
        }
    }
}

I am not certain about the name of SetTextureScale, because it depends fully on the shader it uses. I am also uncertain about just saying: `GetComponent().renderer`. Don't know if that works. But it's worth a try.
