Animate UV Offset in Unity Animation Timeline

[sam_bond]

Hi
All the material parameters are internally stored in an array. It seems that the animator does not show members of type Array.
The solution would be then to create a script that will act as a middle man between the animation and the module:
The script will for example have a float V offset value, editable by an animation. The script will every frame apply that value to yourModule.MaterialSettings[yourMaterialIndex].UVOffset.y
Did this help?

I wrote the following script to try to control the value, but I seem to be getting an error saying that MissingComponentException, there is no Meshrender attached to the Game Object. 

Code:

using UnityEngine;

public class MaterialOffsetController : MonoBehaviour
{
    public float vOffset;
    public GameObject river;
    public int materialIndex;

    private MeshRenderer meshRenderer;

    private void Start()
    {
        // Get the MeshRenderer component from the specified GameObject
        meshRenderer = river.GetComponent<MeshRenderer>();
    }

    private void Update()
    {
        // Update the material's UVOffset.y value based on the vOffset value
        Material[] materials = meshRenderer.materials;
        if (materialIndex >= 0 && materialIndex < materials.Length)
        {
            Material material = materials[materialIndex];
            Vector2 offset = material.GetTextureOffset("_MainTex");
            offset.y = vOffset;
            material.SetTextureOffset("_MainTex", offset);
        }
    }
}

I am setting the script on a empty parent game object and selecting the Curvy Spline Generator as the GameObject. I am pretty sure I am not access the property value correctly.
