Is it possible to override the texture preview?

Hi,

Is it possible to override the texture preview in the inspector? I’ve tried the normal method of a custom editor to no avail.

We use a class derived from ObjectPreview, something similar to this (replace TextAsset with Texture2D):

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

[CustomPreview(typeof(TextAsset))]
public class MyPreviewClass : ObjectPreview
{
    public override bool HasPreviewGUI ()
    {
        return AssetDatabase.GetAssetPath(target).EndsWith(".bytes");
    }

    public override void OnPreviewGUI (Rect r, GUIStyle background)
    {
        // TODO: implementation
    }
}

Thanks, turns out I wasn’t overriding HasPreviewGUI(). For anyone that stumbles across this thread, this code should work:

using UnityEditor;
using UnityEngine;

namespace TextureInspector
{
    [CanEditMultipleObjects]
    [CustomEditor(typeof(Texture2D))]
    class TextureInspector : Editor
    {
        public override bool HasPreviewGUI()
        {
            return true;
        }

        public override void OnPreviewGUI(Rect r, GUIStyle background)
        {
            base.OnPreviewGUI(r, background);
            GUI.DrawTexture(r, target as Texture2D, ScaleMode.ScaleToFit);
        }
    }
}
