Code-Only How to create material with layers?

[Kation]

I use this code to create a layer to a material descriptor.

MaterialDescriptor materialDescriptor = ...;

int[] textureData = new int[layerTexture.Size * layerTexture.Size];
for (i = 0; i < layerTexture.TextureData.Length; i++)
{
    var color = ...;
    color.A *= layerTexture.TextureData.Span[i];
    textureData[i] = color.ToRgba();
}
var texture = Texture.New2D(device, layerTexture.Size, layerTexture.Size, PixelFormat.R8G8B8A8_UNorm, textureData, TextureFlags.ShaderResource);
var textureMaterial = Material.New(device, new MaterialDescriptor
{
    Attributes =
    {
        DiffuseModel = new MaterialDiffuseLambertModelFeature(),
        Diffuse = new MaterialDiffuseMapFeature(new ComputeTextureColor(texture))
    },
    MaterialId = AssetId.New()
});
materialDescriptor.Layers.Add(new MaterialBlendLayer
{
    Material = textureMaterial,
    BlendMap = new ComputeTextureScalar() { Scale = Vector2.One, FallbackValue = new ComputeFloat(1f) },
    Name = layerTexture.Name,
    Enabled = true
});

But then I make a material will throw exception show Error when creating the material [Error: Unable to find material [Stride.Rendering.Material] Error: Unable to find material [Stride.Rendering.Material] ].

Material.New(device, materialDescriptor)

I solve it.
In the layer that material should not use Material.New.
Use new Material { Descriptor = ... } instead.
