TextMesh Pro TMPro text is not visible on a device

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.

 

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

 

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

 

@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

Here is the github repo : https://github.com/Thomas-6freedom/TMPiOS

 

@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

# TextMesh Pro files

[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 : https://github.com/desktop/desktop/pull/7550#issuecomment-546400211

 

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

 

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.

 

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)
