Abstract class to derive from for defining custom GUI for shader properties and for extending the material preview.

Derive from this class for controlling how shader properties should be presented. For a shader to use this custom GUI use the 'CustomEditor' property in the shader. Note that CustomEditor can also be used for classes deriving from MaterialEditor (search for: Custom Material Editors). Note: Only the ShaderGUI approach works with Substance materials this is therefore the recommended approach to custom gui for shaders. See ShaderGUI.OnGUI, ShaderGUI.OnMaterialPreviewGUI, ShaderGUI.OnMaterialPreviewSettingsGUI.

using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using System.Linq;

public class CustomShaderGUI : ShaderGUI { override public void OnGUI(MaterialEditor materialEditor, MaterialProperty[] properties) { // render the shader properties using the default GUI base.OnGUI(materialEditor, properties);

// get the current keywords from the material Material targetMat = as Material; string[] keyWords = targetMat.shaderKeywords;

// see if redify is set, then show a checkbox bool redify = keyWords.Contains("REDIFY_ON"); EditorGUI.BeginChangeCheck(); redify = EditorGUILayout.Toggle("Redify material", redify); if (EditorGUI.EndChangeCheck()) { // if the checkbox is changed, reset the shader keywords var keywords = new List<string> { redify ? "REDIFY_ON" : "REDIFY_OFF" }; targetMat.shaderKeywords = keywords.ToArray(); EditorUtility.SetDirty(targetMat); } } }

OnClosedThis method is called when the ShaderGUI is being closed.
OnGUITo define a custom shader GUI use the methods of materialEditor to render controls for the properties array.
OnMaterialPreviewGUIOverride for extending the rendering of the Preview area or completly replace the preview (by not calling base.OnMaterialPreviewGUI).
OnMaterialPreviewSettingsGUIOverride for extending the functionality of the toolbar of the preview area or completly replace the toolbar by not calling base.OnMaterialPreviewSettingsGUI.
