I'm currently just making a new script with the values I need (tiling/offset), and having it set the values on the material manually at runtime in OnRenderObject or something. Then animate these script values from the Animation window. For example:

using UnityEngine;
using System.Collections;

[ExecuteInEditMode]
public class MaterialAnimation : MonoBehaviour
{
public string materialName = "_MainTex";
public Vector2 tiling, offset;

void OnRenderObject()
{
renderer.sharedMaterial.SetTextureScale(materialName, tiling);
renderer.sharedMaterial.SetTextureOffset(materialName, offset);
}
}

use this script

Animation does not update variables on Windows Phone.

Easy repo. Animate any variable of your mono behaviour script like float and log that variable every update in console. In Editor it is ok on Windows Phone does not update at all..

The issue everyone else is having is probably related to this issue: http://issuetracker.unity3d.com/issues/cant-animate-color-value-of-materials

Unfortunately, they don't seem to be very concerned over this.
I personally can't animate any material values using Legacy or Animator whatsoever.

I have an animation for a material that I have used for a few years. As of 4.3.4f1 I cannot edit the animation. All the parameters for the material are greyed out and will not animate. I'll focus on other parts of the game development but I'd just like to point out that I had no issue ever with this BUT now I do despite nothing being changed from my end/

This bug is marked as fixed, but I am still experiencing this very issue with setting the alpha in the animation window. Anyone else still have this issue? Something I need to download to fix this? I'm on version 4.3.2f1

I've found the issue: this only happens for materials using ShaderLab, the ones with CGShader still work. Even the materials at Unity guys official help (http://docs.unity3d.com/Documentation/Manual/ShaderTut1.html) have this issue. Hope this helps you guys.

This problem is very serious!!!! Why Did not fixed in 4.3.3 version?? Please fix as soon as. : (

After upgrading to 4.3.3, this issue still remains. What's up with that? Why is this bug's status set to fixed if it's actually — you know — not fixed?

This bug is still around. In version 4.3.2f1 I can animate the texture offset if I'm making an animation for an animator component, but not for the animation component.
