Editor script - Find all objects set to lightmap static

Unity Engine
1

I’m trying to select every object in the scene that has the lightmap static flag set. If this makes a difference, I am still using unity pro 4.

I have a export obj script which exports the selected objects with their lightmap UVs so I can paint over lightmaps in substance painter, but I’d like to find a way to get the selection automatically instead of manually selecting all my lightmapped objects.

Can anyone point me in the right direction?

Any luck with this? I am trying to do something similar, but I could also work with all objects that are reflection probe static.

It ended up being easy enough to work out. Below is the script I ended up writing.

Just so you know, I am still using unity 4, so its never been tested on 5 yet.

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

public class SelectLightmapStatic : EditorWindow
{
    [MenuItem("Custom/Select Lightmap Static")]
    static void Init()
    {

        // Find all the lightmap static objects

        Object[] All_GOs = FindObjectsOfType(typeof(GameObject));

        GameObject[] GOArray;
        GOArray = new GameObject[All_GOs.Length];

        int ArrayPointer = 0;


        foreach(GameObject EachGO in All_GOs)
        {
            StaticEditorFlags flags = GameObjectUtility.GetStaticEditorFlags( EachGO );
  
            if ((flags & StaticEditorFlags.LightmapStatic)!=0)
            {
                if( EachGO.GetComponent<MeshFilter>() != null )
                {
                    GOArray[ArrayPointer] = EachGO;
                    ArrayPointer += 1;
                }
            }

        }

        Selection.objects = GOArray;

    }

}

Works like a dream on Unity 5. Thanks!

I was trying to do something similar with Navigation Static objects when I found this post.
Thanks a lot @Gnimmel you saved me time here.

And to contribute to this, here’s my adapted version, using Linq, and the probably new GameObjectUtility.AreStaticEditorFlagsSet method.

using System.Linq;
    static void SelectStaticsByFlags (StaticEditorFlags flagsFilter)
    {
        var allGameObjects = FindObjectsOfType<GameObject>();

        var statics = (from item in allGameObjects
            where GameObjectUtility.AreStaticEditorFlagsSet(item.gameObject, flagsFilter)
            select item).ToArray();

        Selection.objects = statics;
    }

Wow, this is a old thread but I’m glad it helped :slight_smile:
