Bug (Case 1241288) Creating Texture3D asset causes editor crash

This is my 3rd attempt to get this crash through QA, now posting in the forum, which hopefully boosts its chance to get reproduced this time.

Creating a Texture3D asset causes the editor to crash. Please see the attached video, which shows that this works in 2019.3, but causes a crash in 2020.1.

Reproduce

• Create new "3D" Project or open attached project
• Install "Texture3D Atlas Import Pipeline" package from git https://github.com/pschraut/UnityTexture3DAtlasImportPipeline
  
• In Project window right-click and choose "Create > Texture3D Atlas"
• Press Return to confirm the asset name

Actual
Unity editor crashes.

Expected
No crash. This used to work in Unity 2019.3.

 

Still hoping for a reply. Is anybody able to reproduce this crash or is it only me?

 

Seems like we're not really getting further.

I came across a twitter post from @Aras recently, where he shows off new Texture3D preview functionality. So I started to wonder if the crash is related to it.

I found out that I'm actually able to create a Texture3D object, but as soon as I assign it to

Selection.activeObject

, which I believe would then use the new preview/inspector, the editor goes kaboom.

Is this helping you any further to fix this issue?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEditor;
5.  
6. class CreateTexture3DTool
7. {
8.     static Texture3D s_Texture3D;
9.  
10.     [MenuItem("Test/Create Texture3D in memory")]
11.     static void DoMenuItem()
12.     {
13.         if (s_Texture3D != null)
14.             Texture3D.DestroyImmediate(s_Texture3D);
15.         s_Texture3D = null;
16.  
17.         Debug.Log("Before new Texture3D");
18.         s_Texture3D = new Texture3D(16, 16, 3, TextureFormat.ARGB32, true);
19.         Debug.Log("After new Texture3D");
20.  
21.         Debug.Log("Before Selection.activeObject = s_Texture3D");
22.         Selection.activeObject = s_Texture3D; // this is causing a crash
23.         Debug.Log("After Selection.activeObject = s_Texture3D");
24.     }
25. }
26.  

 

I can offer to test a custom Editor build if that would help. For example if you add additional logs/asserts or whatever you prefer around code that might cause the problem?

What makes me believe it's Not really a problem with my setup is that it works just fine in unity 2019.3.

 

Have you tried in the latest beta? I tried to follow your setup in b9, I don't get crash, not even warning.
However I have a "Custom NUnit" package in my project by default, because some of the packages you and me have depend on it. I'm not sure though if it was the same in b6 which you have showcased here.

BTW, I have a similar issue, which is only reproducible by me and it involves the beta and some packages. In some cases adding/updating the Collaborate package crashes my b8 and b9. Obviously I'm not sure if it has anything to do with your case, it's just a shoot in the dark.

 

Hey thanks for the reply!
I haven't tried the most recent beta, but I'm able to reproduce the crash in Unity 2020.2, so I doubt latest beta fixed it. Good idea with the packages, but today I figured out I'm also able to reproduce the crash without my Texture3D Import Pipeline package and just these two lines of code:

var tex = new Texture3D(16, 16, 3, TextureFormat.ARGB32, true);

Selection.activeObject = tex; // this is causing a crash

Thanks for the reply too!

Unfortunately I don't. I'm working from home office and only have this one rather outdated machine. Since it seems to work everywhere but on my PC, I guess it would also work if I try it on a different PC.

• It works in 2019.3.
• It does not in 2020.1 and 2020.2.
• I've updated graphics drivers.
• I've DirectX 12.
• DxDiag does not find any problems.
• Perhaps the Feature Levels: 11_0,10_1,10_0,9_3,9_2,9_1 are not sufficient anymore?

The DxDiag report shows several "Not Supported" entries, maybe Unity requires something my hardware does not support now?

Have you looked at the crash.dmp file? I hoped it would help or at least gives some ideas where to put additional asserts/printfs.

That's a good example where having Unity source code access would pay off, then I could just fix it myself or at least add a better error message and don't desperately need to cry for help.

 

Thanks so much for the help! I've updated Case 1241288 with the crash.dmp and editor.log files, I used this code to reproduce the crash.

Please note the crash does not seem to occur while creating the Texture3D:

var tex = new Texture3D(16, 16, 3, TextureFormat.ARGB32, true); // works fine

... but after assigning it to the selection:

Selection.activeObject = tex; // this is causing a crash

... and this also does not crash immediately at that line. The Debug.Log after that line still occurs. If I remove the selection assignment and only create the Texture3D object, it does not crash.

 

@Aras I'm pretty confident it's related to the Inspector. If I close the Inspector window and execute this code:

Code (CSharp):

1. var tex = new Texture3D(16, 16, 3, TextureFormat.ARGB32, true);
2. Selection.activeObject = tex;

... no crash.

If I then open an Inspector window, the crash occurs:

The crash occurs, because Selection.activeObject still points to the created Texture3D object and the Inspector tries to display it or something related to it.

 

In the mean time I have tested this problem on an Intel UHD 620 and on a Geforce MX150 (Razor Blade laptop). Neither had crashed, unfortunately. (Attached my dxdiag if you want to compare)

 

I'm super grateful that you looked into it and I know from first hand experience that fixing bugs can be awful to impossible if you can't reproduce it locally. So this wasn't a problem at all for me. I actually think you found the issue really fast.
