Material.SetFloat not updating in play-mode.

I'm trying to update

_Fill

property of my shader using

Material.SetFloat

property. It works just fine, however it's not updating in play-mode but only after stopping.
Using

setMaterialDirty()

on

Image.material

didn't work.

Code (CSharp):

1.  public class OrbFillUpdater : MonoBehaviour
2. {
3.      public IntegerReference Variable;
4.      public IntegerReference Max;
5.      private Material material;
6.      private void Start()
7.      {
8.          material = GetComponent<Image>().material;
9.      }
10.      private void Update()
11.      {
12.          float value = Mathf.Clamp01(Mathf.InverseLerp(0, Max.Value, Variable.Value));
13.          material.SetFloat("_Fill", value);
14.      }
15. }

And here is

_Fill

property.

Code (CSharp):

1.  _Fill("Fill Amount", Range(0, 1)) = 1
2.  
3. float _Fill;
4.  
5. fixed4 frag(v2f IN) : SV_Target {
6.      // ... Code
7.      if (IN.texcoord.y >= _Fill)
8.      {
9.          if (IN.texcoord.y + (noise.r - 0.7) * _NoiseStrength >= _Fill)
10.          {
11.              color.a = 0;
12.              layer1.a = 0;
13.              layer2.a = 0;
14.              layer3.a = 0;
15.          }
16.      }
17. }

 

Still looking for a way to fix this.
Maybe this is a Unity bug?
