is this a bug?

Question

Unity 2021.1.15f1

Converting material to Lit with HDRP The displayed Amplitude value of HightMap is different from what it actually looks like. When you re-enter the same value, it returns to normal. When I checked the change value in debug mode, _HeightPoMAmplitude is the value shown in the inspector window. Actually, the _HeightAmplitude value and the HeightCenter value are not properly entered.

I later found out about this problem and had to run some code to re-update the _HeightAmplitude values of all HDRP/Lit materials in the project. If it's a bug, please fix it.

If you look at Lit.Shader // Caution: Default value of Height Amplitude must be (_HeightMax - _HeightMin) 0.01 It is stated In my case, I had to do _HeightPoMAmplitude 0.01 to get the correct value.

This is how I temporarily solved it

 void Refresh()
 {
     DirectoryInfo Di = new DirectoryInfo("Assets");
     FileInfo[] file = Di.GetFiles("*.mat", SearchOption.AllDirectories);

     foreach (var item in file)
     {
         string filePath = Path.Combine(item.Directory.FullName, item.Name);
         filePath = filePath.Substring(filePath.IndexOf("Assets\\"));
         Material target = (Material)AssetDatabase.LoadAssetAtPath(filePath, typeof(Material));
         if (!target || target.shader.name != "HDRP/Lit" || target.GetFloat("_HeightAmplitude") == 0)
             continue;
         target.SetFloat("_HeightAmplitude", target.GetFloat("_HeightPoMAmplitude") * 0.01f);
     }
 }
