    Hi,
    Looking for some reference for writing custom ShaderGUI's for shaders made in shader graph like combining properties in dropdown menus etc. in inspector view
    This:
    https://docs.unity3d.com/Manual/SL-CustomShaderGUI.html
    isn`t very helpfull and im having issues to find working samples, nothing i've tried worked...


    This is my latest attempt:
    Code (CSharp):
    1. public class ShaderGUI_Skybox : ShaderGUI
    2. {
    3.     override public void OnGUI(MaterialEditor materialEditor, MaterialProperty[] properties)
    4.     {
    5.  
    6.         bool showstuff = false;
    7.  
    8.         base.OnGUI(materialEditor, properties);
    9.         EditorGUI.BeginChangeCheck();
    10.  
    11.         if (GUILayout.Button("Select GUI Color"))
    12.         {
    13.             showstuff = !showstuff;
    14.             Debug.Log(showstuff);
    15.         }
    16.  
    17.  
    18.         if (EditorGUI.EndChangeCheck())
    19.         {
    20.             Debug.Log("End");
    21.             if (showstuff)
    22.             {
    23.                 // Sun
    24.                 EditorGUILayout.LabelField("Sun", EditorStyles.boldLabel);
    25.                 string[] SunReferences = { "_SunScale", "_SunConvergence", "_SunIntensity" };
    26.                 foreach (string Reference in SunReferences)
    27.                 {
    28.                     MaterialProperty SunReference = ShaderGUI.FindProperty(Reference, properties);
    29.                     materialEditor.ShaderProperty(SunReference, SunReference.displayName);
    30.                 }
    31.             }
    32.         }
    Debug.Log works but the GUI in inspector does nuthing and im totally lost :)...

    Got it,
    EditorGUILayout.BeginFoldoutHeaderGroup(true, "Dropdown");
    and
    EditorGUILayout.EndFoldoutHeaderGroup();
    creates the dropdown menu i was looking for

    Code (CSharp):
    1.  
    2. public class ShaderGUI_Skybox : ShaderGUI
    3. {
    4.     bool showPosition = true;
    5.     string status = "Settings";
    6.  
    7.     override public void OnGUI(MaterialEditor materialEditor, MaterialProperty[] properties)
    8.     {
    9.         showPosition = EditorGUILayout.BeginFoldoutHeaderGroup(showPosition, status);
    10.  
    11.         if (showPosition)
    12.         { // Sun
    13.             EditorGUILayout.LabelField("Sun", EditorStyles.boldLabel);
    14.             string[] SunReferences = { "_SunScale", "_SunConvergence", "_SunIntensity" };
    15.             foreach (string Reference in SunReferences)
    16.             {
    17.                 MaterialProperty SunReference = ShaderGUI.FindProperty(Reference, properties);
    18.                 materialEditor.ShaderProperty(SunReference, SunReference.displayName);
    19.  
    20.                 //EditorGUILayout.Separator();
    21.             }
    22.  
    23.         }
    24.         EditorGUILayout.EndFoldoutHeaderGroup();
    25.     }
    26. }
    27.
