TMPro text is not visible on a device

[apocalypshuk]

Hi guys, have a question about TextMeshPro. I’ve generated a custom SDF font and created few material presets. When I’m testing the game in unity editor - everything works fine, all texts are visible. But when I run the game on my OnePlus6 - texts which are using one particular material preset are not visible. Other texts, which are using the same font, but different materials works fine. When I added another one material - different preset become invisible on a device. So I think it’s related to the resources loading time/order. By the way, all texts are visible on my other phone - MeizuU10. I’m using Unity 2018.3.6 and TMPro 1.3.0. Please, advise, I have no idea what I’m doing wrong.

Are you using a mixture of and objects where these objects share the same material presets?

Yes, one of the material presets is used both in TextMeshPro and TextMeshProUGUI components.

Yes, one of the material presets is used both in TextMeshPro and TextMeshProUGUI components.

This behavior is the result of the Mesh Renderer which is used by the normal component and the CanvasRenderer used by the objects fighting over the ZTest on the material.

The solution is to have a separate set of Material Presets for Canvas objects and Mesh Renderer objects.

Wow, now I got it. I’ll do separate materials. Thank you very much!

@Stephan_B Hello. I have the same issue. I have only TextMeshProUGUI component but I have some WorldSpace canvas and some ScreenSpaceCanvas. Should i do separate materials for SS canvas and WS canvas ?

using 2019.2.9f1 + Unity Cloud Build iOS + TMP 2.0.1

(don’t have the issue in Editor and in my android build)

Thank you

For testing and to help narrow down the potential source of the issue, I would most certainly test using a different set of Material Presets.

@Stephan_B
I made a new fresh project with

• only one camera
• one canvas
• one TextMeshProUGUI
• I removed a lot of Packages. Only kept Package Manager, Unity UI, TextMeshPro & Visual Studio Code Editor
• I created an iOS 11.0 build
• Unity 2019.2.9f1
• using Unity Cloud Build
• using Very Low Quality settings (EDIT : I also tried with Ultra settings. Same issue.)

The text do not show on my iOS 13 iPad

In the project linked above, the TMP Essential Resources are not present. For these tests, did you import the TMP Essential Resources?

If you did import the TMP Essential Resources, what TMP shader is assigned to the text object?

@Stephan_B WOW ! Thanks !! I did not realised it’s not pushed !
Look at my screenshot, it’s in my project !

I looked into my .gitignore and there is this line :
https://github.com/Thomas-6freedom/TMPiOS/blob/master/.gitignore

[Aa]ssets/TextMesh*Pro/```

I use the default GitHub Unity3D gitignore file from Github Desktop !
I'vr created an issue on their repo : https://github.com/desktop/desktop/issues/8527

Why did they do this ?!

I will try again by commenting this line.

(of course I use the default LiberationSans material)

I commented the incriminated line and it’s working flawlessly. Thank you for your help and your availability @Stephan_B !

EDIT : They fixed the issue : update gitignore submodule to latest version by Bassadin · Pull Request #7550 · desktop/desktop · GitHub

Thanks @Stephan_B . This issue was a real headache for me. To makes things interesting my problem was that my android phone build was working just fine(Samsung phone). In the editor, game was fine as well. Only my tablet(Samsung tablet), was having an issue. One scene, TMPro would not render. After I have deleted non-UI TMPro gameObjects in the game, the UI text rendered again. Hope it helps others. Thanks

The above was likely related to having a mixture of and objects that share the same material. Since the MeshRenderer used by objects and the CanvasRenderer used by objects often have different ZTest requirements, you end up with a conflict where these two renderers are fighting / changing the ZTest on the material. This can result in text not being visible.

The solution if you need to use a mixture of and objects is to have a separate set of Material Presets for each renderer type.

Hello!

I know this mistake is constantly reported and most of the times it has to do with using TextMeshProUGUI and TextMeshPro together, I’ve read some posts about this same issue, but I’m not using the same materials and I’m having some odd problems, some of the TextMeshPro and some of the TextMeshProUGUI won’t show, not all of one or all of the other.

I’ll post some screenshots to explain it better:

For all my TextMeshPro on my World Canvas I’m using the font Alata-Regular-Outline 40 SDF World Canvas

While for all the UI I’m using Alata-Regular-Outline 50 SDF UI

An just as a final effort, I’ve added an extra font for the oddest issue,Alata-Regular-Outline 54 SDF UI, here on the screenshot I’ve two TextMeshProUGUI selected with the same settings: (PS all the text on this screen is using this same font asset, and the icons will change randomly)

And this is how it shows on the final build

I also find some issues with the World Space canvas, the yellow bar should present a name above it, just like the grey bar on it’s side.

All the text using Alata-Regular-Outline 50 SDF UI is working fine on the build, and if I play on the editor I find no issue at all, all enemy names appear and all text on that screen “Level Completed” show correctly!

PS: I’m using the localization asset, that’s why the languages are different from the editor and the play mode

I think that’s all! Glad to hear your thoughts!

Just to confirm this issue only occurs in the build?

Is this a Desktop build and if not what platform?

Any chance you can submit a bug report with project? If you do, please provide the case # once you have it.

Hello Stephan, thank you for your help, at the end it didn’t have anything to do with the TMP asset, it was something related to the Localization package, I found the error, thanks for your help.

Just for anyone else running into this, what was the issue with the Localization Package?

How did you resolve this?

[BeorGames1]

Oh, I had to build the Adressable again, I thought it had to be done only once, not every time I add new text to the game, so it wasn’t showing anything because it tried to translate the text and couldn’t find it, so it returned an empty string, found it adding a debug.log on the translation returned and running it on adb logcat, because on the PC it was working fine.

Hi, I can confirm that this still happens with Unity version 2021.3.X
using separated materials fixed the issue, but I think that is something that should be fixed on the Unity side…

Hi, @Stephan_B I wonder Why does this issue only occur on the device and not in the editor?
Under what circumstances does this issue occur?In my case, within the same scene, both TextMeshPro and TextMeshProUI display correctly, but the TextMeshProUI under the “DondistoryOnload” node is not showing up. (They are all using the same material)
