If you implement OnInteractivePreviewGUI then this will only be called for non-interactive custom previews. The overidden method should use the rectangle passed in and render a preview of the asset into it. The default implementation is a no-op.

Note: Inspector previews are limited to the primary editor of persistent objects (assets), e.g., GameObjectInspector, MaterialEditor, TextureInspector. This means that it is currently not possible for a component to have its own inspector preview.

using UnityEngine;
using UnityEditor;

public class GameObjectEditorWindow: EditorWindow { GameObject gameObject; Editor gameObjectEditor;

[MenuItem("Window/GameObject Editor")] static void ShowWindow() { GetWindow<GameObjectEditorWindow>("GameObject Editor"); }

void OnGUI() { gameObject = (GameObject) EditorGUILayout.ObjectField(gameObject, typeof(GameObject), true);

if (gameObject != null) { if (gameObjectEditor == null) gameObjectEditor = Editor.CreateEditor(gameObject);

gameObjectEditor.OnPreviewGUI(GUILayoutUtility.GetRect(500, 500), EditorStyles.whiteLabel); } } }
