Everything Canvas turns pink, when playing windows build

Hello!

Someone knows why this happens? I've googled a bit, and I've found an interesting lead: this sort of thing happens when the shader is not pre-loaded. But... if this is happening only with uGUI elements, so... I've got clueless. First time this happens to me.

 

nobody?

 

(SOLVED) Looks like my project settings got corrupted. Deleting the folder and restarting unity solved. Now I will try to re-do this without messing my game.

 

Hi Zimbres, I am having the same problem you had with canvas turning pink on build, just wondering how you solved it through Project settings?

 

I can't seem to fin that option in the File -> Build Settings.
Where exactly is the option of including shaders ?

 

Edit/ProjectSettings/Graphics. Fill out the Always Included Shaders. Starting a new project size = 7, Legacy Shaders/Diffuse, Hidden/CubeBlur, HiddenCubyCopy, Hidden/CubeBlend,Sprites/Default,UI/Default,UI/Default Font.

 

This fixed the problem

Thanks a lot sir

 

Thanks! This helped me, too. The little gear at the top of the inspector page for built in shaders --> Reset

I was having trouble with the GvrFPSCanvas prefab because it was pink! But this did the trick!

 

Dude you are awesome !!!

 

Wow, It's true. I can't believe it.
The problem is SOLVED when I do "reset" in Graphic Settings!!

 

Thank you very much!!

 

thanx bro

 

That did it! Thanks!

 

@karl_jones Thank you so much!

 

thanks

 

Greetings!

Forgive me for adding to this threads, I am very new to Unity and also struggling with the dreaded pink screen...
I am attempting to open a project file that a previous co-worker built and saved in a Shared Drive. When it opens.. nothing but PINK. Under Project Settings Graphics I have the following :
6, Legacy Shaders/Diffuse, Hidden/CubeBlur, HiddenCubyCopy, Hidden/CubeBlend,Sprites/Default,UI/Default,UI/Default Font.

I attempted to reset graphics but I have had no success, any suggestions?
Images of Settings attached

 

Same as PCenrich.

I am getting pink rendering on Unity cubes, only in builds not in the editor.

I have deleted the Project Settings and had Unity recreate them. No luck.

I double checked the Project Settings > Graphics > Graphics Settings > Always Included Shaders and I have the following:

After resetting I have the following:

6
0 Legacy Shaders/Diffuse
1 Hidden/CubeBlur
2 Hidden/CubyCopy
3 Hidden/CubeBlend
4 Sprites/Default
5 UI/Default

After running the program in Unity, it remains the same. No pink.

After building the program, it switches to this and executes with pink:

7
0 Legacy Shaders/Diffuse
1 Hidden/CubeBlur
2 Hidden/CubyCopy
3 Hidden/CubeBlend
4 Sprites/Default
5 UI/Default
6 Hidden/VideoDecode

Any ideas?

 

For anyone that couldn't fix this by resetting the shaders: I was able to fix it by changing/updating .NET libraries on Visual Studio Installer.

We were building the exact same project to Switch on 2 different PCs: one of them would work perfectly, the other would only produce magenta screens with a bunch of shader error/warning messages when trying to build from Unity 2018.3.0b12 (building from Unity 2018.2 worked on both). Resetting the shaders (or any of other tons of things we've tried) had no effect.



So what we did was to export the configuration from the PC where builds were fine, importing it on the other PC, and the next build magically worked. Unfortunately I didn't take note of the previous configuration to know which component(s) caused the issue.

If you don't have a working configuration to export, I'd suggest modifying your .NET environment, updating and/or adding components. This is what it looks like on mine:



I hope this helps!

 

@futurlab_peterh Thanks, it helped me

 

Can anyone recommend a workaround for those of us (i.e. me) using VS Code instead of the full Visual Studio? Resetting shaders didn't work. Sounds like a fix is coming in 2019.3 but I really need a working project soon.

 

Oh, thank you!

I really have been bumping my head on the wall half a day, and of course it had to be something shader-related.

I cleared that list months ago, I totally forgot I've been overzealous with "optimization"

After adding the first 7 suggested by pressing the reset cog button on the Graphics settings, I undoed that, added them back manually, and after the next build the list got automatically expanded to this one:

(Unity 2019.2.9f1, targeting Android)

I'm really not sure about the reason videocompositing shaders got added, (probably I left some builtin package enabled), but I learnt not to mess too much with builtin packages especially with an impending deadline

I really wished Unity would have warned me about those shaders being missing, since I was clearly using them and before building for Android!

I guess it's not that easy to determine tho, otherwise such feature would be already there

 

I solved this problem with 2 step.

1- Project Settings/ Graphics --> Reset (in top of inspector)
2- Add Sprites/Diffuse in Always Included Shaders manuel.

 

What solved my issue was creating a prefab and instantiating game objects via prefabs rather than primitives... it likely does automatically some of the same things found in other solutions here (such as including a shader and whatnot).

 

dude a simple restart helped the UI come back

 

Thanks dude!

 

Thanks a lot

 

I saw the pink-screen-of-death on iOS device when updating to Unity 2019.4.31 (latest LTS at the time).
I had never seen this issue before now.
My graphics settings were all correct (tried the 'reset' option in GraphicsSettings) and also confirmed Metal graphics API in PlayerSettings.
This is an old project that doesn't use the new render pipelines.
At runtime I saw messages like:

"WARNING: Shader Unsupported: 'Sprites/Default' - All passes removed"

Looking at the release notes of 2019.4.31 I saw the following line:

"Graphics: Reduced main thread hitching caused by Shader loading."

That looked suspicious so I downgraded my project to Unity 2019.4.30 and now everything is fixed. I didn't investigate any further.
Just mentioning this here in case someone from Unity wants to chase it up.

 

I have two 3D projects which are also experiencing this pink screen issue.

Project 1:
- Unity 2019.4.30f1: everything works perfectly
- After upgrading to Unity 2019.4.31f1: pink screen when launch (on iOS, Android devices; normal on Unity Editor)

Project 2:
- Unity 2020.3.18f1: everything works perfectly
- After upgrading to Unity 2020.3.19f1: pink screen when launch (on iOS, Android devices; normal on Unity Editor)

Worth to note that in both projects:
- The pink issue does not happen if building for iOS/Android from Unity Editor
- It only happens when I build with command line (headless) mode

There's something changed since the new Unity versions that causes this? I hope someone from Unity can help.

 

I notice this difference in the build log while building in headless mode on the terminal:

With Unity 2020.3.18f1:

With Unity 2020.3.19f1:

Note that it's always "0 variants" with Unity 2020.3.19f1 (which results in the pink issue). It looks like shaders are not compiled at all. I wondering why that?

-----

Another observation:

If I remove the "-nographics" flag in the build command, the resulting build works well (no pink issue), the log output looks like in 2020.3.18f1. Problem SOLVED!!

 

Oh very interesting. In my previously mentioned case I am also building in headless mode.

 

Thank you for solving my problem, your answer was very helpful
