Texture problem : Graphical Corruptions - Need Help

Hello all,

As stated on the title, I have a real weird problem showing on textures. After looking everywhere in my scene, and in Unity forums, I still can't figure out how this happens.

Here is the result of my scene in Unity Editor, like I expect to have in build :


Here is the result when I simply build :

• I tried this on Unity 5.3.3f1, and 5.3.4f1, and builds on PC 64x.
• The graphical corruption only occurs in build, never in editor.
• Corruptions shows up only on textures using Unity 5 Standard Specular.
• In my scene, I used only Unity 5 Standard (simple and specular) Shaders. And I only have one custom script for camera control (a simple free cam).
• All textures are DTX5 compressed.
• The more I add textures in the scene, the more I can see corruptions showing up randomly. I obtained this result while having about 500 textures in the scene.

And this is one of the texture (shown broken in build) properties when selected in Unity :


Is this a Unity known bug ? Please I need help on this.

 

Finally (joke,I wish you had not to deal with this bug) another person with this problem.
We have had this issue since 5.3.0 and still having it on 5.3.4p1.

We think it may be caused by a problem with Unity while it builds the assets because it happens on several different materials from standard to speedtree and sometimes we have spotted other textures in the place of the one where there were artifacts.

Our resource.assets.ress is 4.7GB. On 5.2 it was 2.5GB. We don't know why and we think it may cause by surpassing the limit of 4GB as there was a similar limit on Unity 4.x but lower, unfortunately we couldn't find any mention of that in the manual.

Building only the main scene doesn't present artifacts where are usually shown: the resource.assets.ress size i 3.4GB.

We managed to make a build with the file size lowered to 4.3GB and there seems to be less textures having these problems.

 

Did you guys make an error report to Unity Tech?
It looks to me like some rendertextures used internally by Unity for lighting get pushed out of graphics card memory when there are a lot of other textures. So with less memory on the graphics card it would happen even sooner.

 

Seeing your answer made me have the same thought

Well, same thing happens here, but not sure it has to do with build size since I did builds of other scenes with a size of 8Gbytes without any problem. Moreover, each time you want to lower build size, you remove more meshes, which envolves having less textures in the scene.

Not yey, I wanted to start by forums. I will do if nobody can help by the end of the day.
Here is my PC config :

• Graphics : NVIDIA GeForce GTX 970 with 4096Mbytes Type: GDDR5.
• Memory : 16 GBytes DDR4.
  
• CPU : Inter Core I7 6700K.

 

yes we did few days ago.

I don't know but as I said, building the main scene only doesn't present any problem.

We have this problem on several configurations GTX 970, GTX 750ti, GTX 560 and another one I don't recall

 

Have any of you been able to solve this issue?

I filed a bug report but so far no response, not even an acknowledgement of the issue. Another QA guy told me though they weren't able to repro and if someone knew how to repro this issue it might help (but I assume by "repro" they mean with a lightweight project, not a multi-GB full project where "anything" could cause the issue).

 

having resource files below 4GB "solved" it.
Our ticket has been marked as resolved because we used this workaround even it the issue is still there. I'm very disappointed.

 

Yeah, if it's not a mobile platform or at least Windows it seems like support is a lot worse

Anyway, are you talking about single resource file size limit to 4 GiB or all the resource files together below 4 GiB? We never had a single file above that limit but still experienced this issue.

 

a single resource file below 4.
The game is on Windows

 

Hm, ok, we never had a single one over 4. Wonder if it's really the same issue then.
Also, are you saying you actually got the issue on Windows? So far I thought this was OSX only?

 

Got a response today saying they think it's related to a bug in the deferred renderer ( https://issuetracker.unity3d.com/issues/osx-deferred-rendering-causes-lots-of-artifacts ) which is supposed to be fixed with 5.3.6 at latest (but most likely also in a patch release before that).

 

My issue happened on Windows 10, Directx 11 and an Nvidia card.

 

I had an issue similar like this, but it wasn't deferred rendering (I posted about the issue here http://forum.unity3d.com/threads/broken-output-color-on-mac-build.406799/). And yes, it was OSX only problem. I've found the biggest resource file is resources.assets.resS and it's under 4 GB. Still don't know why.

UPDATE
Was resolved! Tried to build the Mac using x86_64 architecture output

 

I am having the exact same problem here, I have an asset that is 5.2 gig. Building on windows with Unity 5.4.2f1. It really sucks not being able to make a build to test anywhere... Anyone know if this got accepted as a bug again? I will re-report if not, we need a fix.

 

I will see if x86_64 solves it for me!!! that 4 gig limit could well be a 32 bit thing, in fact Im almost certain now, fingers crossed, thanks for the tip!.

 

Damn 64 bit does not fix it.

 

Nor does an update to 5.5 beta ;-(

 

Having the same problem, resource assets under 2gb still no fix

Does having a uncompressed texture in the resources foldoer creates a problem?

 

You are not alone. I recently ran into the same problem:
https://forum.unity3d.com/threads/textures-messed-up-in-windows-build.440675/

If I have more than 4GB of textures in my Windows build of my game, then some of the textures will be all messed up, even though the textures look perfectly fine when playing the game through the Unity Editor.

I am guessing there is a 32bit addressing bug in the Unity standalone build, so it cannot locate past 4GB of textures in the build. I temporarily "solved" the issue by using an asset called "Build Report Tool" to track down a list of the largest textures in my project, and then I deleted all of the textures that I did not need in my game at this time. As soon as I had less than 4GB of textures in my build, then all of the broken texture problems were magically fixed.

 

The issue does not seem to be related to total assets in the Resources folder. The issue seems to be a hard limit of 4GB on the total textures in the build. Grab the "Build Report Tool" asset. When you build your project, it will show you total texture size in the build under "Size Stats". It will say Textures, Sounds, Meshes, etc under "Used Assets Size Breakdown" on the "Size Stats" section. If the total size of Textures exceeds 4GB, you will run into the problem.

 

I'm not sure how to issue a Ticket, or maybe should @some Unity Dev Here

 

@Aras @Joe_Robins @antenna tree

Please view the posts above, there seems to be a 4GB texture limit on 64bit Builds.

 

Yeah, the problem here is that the bug only shows up in large projects. It is hard to make a small repro case to submit as a bug report when the problem literally only happens in large projects. Somebody from Unity needs to comment on these threads. I did submit a bug report, but I did not submit my entire project since the source for that project is over 30GB. I just submitted links to the forum threads.

 

does that mean this wont be "fixed"? we should move to asset bundles? damn really cant be bothered doing that lol.

 

Thanks i will give that a read, I am presuming there is some automated way to make asset bundles, and some convenient way to still work with the files etc and not have to make them each time, and certainly to not have to load things from code. Seems like a bit of a workaround that could cause us to focus on this and not the fun part of making the game, indeed it has already stalled everything for me just weeks before I was due to release a demo, now I cannot. Anyway time to learn asset bundles I guess ))

 

That looks great, I will get started with it.

 

your the most helpful unity dev I know good luck to ya

 

I still have these issues, even with the new asset bundle graph tool (excellent idea by the way guys) as you can read here https://forum.unity3d.com/threads/assetbundle-graph-tool-1-0-release.437443/#post-2997914

So I am still waiting for a "fix" on this.... Only problem is I might die waiting

 

anyone ever get around this? seems silly I have waited a year to make a build and I still cannot!!! I find the Asset Bundle Graph Tool is basically unusable too right now. Unity has so many bugs stopping me move forward, and it has wrecked ALL animations in my game too.. tough times to be a unity dev ;-(

 

@radiantboy Does this limitation only apply to textures in a resources folder or is it anywhere in the project hierarchy?

p.s. Don't worry, you probably know how it is with development on Unity by now, it goes in cycles, ups and downs. You're probably in the soul-crushing "stuff not working" period, but the light will return lol, the exciting, creative phase will come back around again.

That animation thing... I seem to remember reading somewhere that a new version of Unity introduced an extra bone for humanoid rigs (another spine bone I think) to more closely resemble something like 3ds Max biped for example. Perhaps this is related?

 

Hey man Thanks for the words of encouragement, looking forward to getting back into that exciting phase for sure!! Unity can demoralise at times, but of course it can do the exact opposite too most of the time!..

The 4 gig thing is basically when you make a build, if any of your .asset files exceed 4 gig of textures then I think it happens.

Animation, im not sure someone just told me to try reimporting the avatars. I would assume if they added another bone, they would not break backward compatibility with existing animations, or they would wreck every game out there. I dont see anyone complaining about it, so I am assuming it is just my project got messed up somehow (not that suprising the amount of times unity has crashed and forced reimports). I believe new animations I have recently imported work, Im gonna try reimporting the avatars on broken anims and see if it works.

 

If that's the case, I'm due a headache as well...

 

Yep, anyone with any largish game will get it, still happening in unity 2017 beta 1. If you use asset bundles apparently it goes away, I am just waiting for the asset bundle graph tool to mature a bit to try that route again, but it appears that it is not that easy to use for huge projects currently imho. It would be great if it could automatically just build assets from a single scene, but it doesnt appear to work that way.

Thankfully my anims are fine after a reimport, so only 2 bugs stopping me build right now, this one with the graphical corruption, and another that hangs during building light phase when making a build.

 

Vote it up guys https://issuetracker.unity3d.com/issues/standalone-corrupted-textures-in-a-huge-project

 

Makes you wonder how they managed to build Wasteland 2 - game is enormous. Obviously was made using an older version of Unity as well...

 

Good point, I guess at that angle everything can be lower res and lower poly.

 

Thank you all for your replies.

Not really a fix, but I figured out how to bypass it. It seems I was having too much BIG textures (2K and 4K resolutions).
So when I did my optimization pass on the scene dividing all textures by 2 or 4, there was no more graphical corruptions.
Also you must be careful on platforms with limited graphical memory like on consoles (PS4 and XboxOne).

Good luck all

 

Hi, I m having the same issue, https://postimg.org/image/4m6yzrdk23/

I need help. I have read about asset bundle, ressources folder, and textures trim. But i m not sure how to start to fix this.

If i remove from hierarchy the last prefabs i added to my game, i dont have the issue. So maybe its texture limitation problem. How can i be sure ? thanks for helping me.

 

Hi. Thanks so much for reply.

Log file here : https://www.dropbox.com/s/lnv22o5fajjoc9a/Editor.log?dl=0

i dont see output files in folder because i dont crash, my game run but with messed up textures.

Thanks for helping me , your guidance is very much appreciated.

Hi.
I fixed the issue by resizing all the textures that were in 4096 to 2048 .

https://postimg.org/image/eqt72qcaf/

It seems working now. I have to check quality in game.

Thanks.

 

im getting some weird glitches like this even when I only build out one level of my game and the biggest .res is 1.7 gig. Im not exactly sure it is the same bug. Is this the same thing? @karl_jones https://www.dropbox.com/s/nwuvmib0yfxilk1/unityfuckup.jpg?dl=0

 

What do you mean you deleted all the textures? Does the textures that are in project folders count too? Like you have 100 textures but in scene they are 50..you use just 50.. does the other 50 counts too that are in the project but not used on some mesh?

 

Same problem on 32bit?

 

What do you mean? You gave up all 4k resolutions on ALL textures ? And made them ex. 1024??? ... im so pissed at Unity right now!! Cant understand that there 2018 now and still not a real fix.. like hello everybody wants 4k
