StencilMaterial class
A couple of days ago I stumbled upon the StencilMaterial class located in the UnityEngine.UI namespace. According to its own description, it is a "Dynamic material class that makes it possible to create custom materials on the fly on a per-Graphic basis, and still have them get cleaned up correctly". This sounded promising so I started searcing the web about how to use it, but to my surprise I couldn't find anything about it anywhere. I tried this code, but it instantly closed unity everytime i tried running it.
public Material instancedMaterial;
public int ID;
public bool initialized;
[ExecuteInEditMode]
protected override void OnEnable()
{
if (!initialized)
{
ID = Mathf.Abs(Guid.NewGuid().GetHashCode());
Material advancedMaterial = (Material)AssetDatabase.LoadAssetAtPath("Assets/Materials/AdvancedSprite.mat", typeof(Material));
instancedMaterial = new Material(advancedMaterial);
instancedMaterial.SetColor("_TestColor", color);
StencilMaterial.Remove(instancedMaterial);
//Material of the Graphic compoonent
material = StencilMaterial.Add(instancedMaterial, ID, UnityEngine.Rendering.StencilOp.Keep, UnityEngine.Rendering.CompareFunction.Disabled, UnityEngine.Rendering.ColorWriteMask.All, 255, 255);
initialized = true;
}
}
Any tips on where to start? I am using this for my UI to send unique data to elements with the same material, since MaterialPropertyBlock did not work on UI based meshes.
