Text 3D causes crash on Android

[Automaticow]

It seems as the 3d text component, and the normal 3d text, causes a game crash when running on android platform. The resulting error log is listed below.

Steps to reproduce:

1. Enable the “Text 3D” plugin, and restart editor.
2. Create an empty level
3. Add a “Text 3D” element
4. Launch on an android device with editor “launch”
5. Observe the game crash immediately.

My setup:
Ue4.25 - Windows 10
android ndk 21.1.6352462
Device: Sony xperia XZ1 compact

Did you resolved this issue? I’m having the same problem in Quest build whenever I’m using Text3D

If you’re using Oculus UE fork, you can just patch your StaticMesh.cpp file manually until Oculus updates their fork. I tested this with Oculus 4.27.1 and it’s working ok.
