Shader material resources not exported in Android APK

[ygingras]

Tested versions

• Reproducible on Godot 4.2.1 with published packages and with self compiled editor

System information

Linux Ubuntu 23.10 on Wayland with Godot 4.2.1

Issue description

Shader Material resources are not included inside an exported APK package for Android.

The editor correctly produces and caches those sub resources, but godot in headless mode fails to produce and include them in the exported APK package. When running in an automated CI/CD, such as the F-Droid build pipeline, it's not always possible to start the editor before generating the APK package.

Steps to reproduce

git clone https://gitlab.com/ygingras/godot-shader-res-repro.git
# open the project in the editor, install android export templates, close editor
cd godot-shader-res-repro
rm -rf .godot
godot --headless --export-release 'Android' repro.apk
apksigner sign --ks path/to/dev-keystore repro.apk

# connect an android device via USB
adb install repro.apk
# launch the apk on the mobile device
# the screen is plain grey or greyish blue rather than animated water

The Sprite2D uses a water material that includes a shader and two noise textures. Those display correctly to produce an animated water look when running inside the editor.

To see if the problem is present without installing on a device, we can look at assets/.godot/exported/133200997/export-c4c4fea8197baf42b15b4e3ed1b00e5a-water_material.res (or similar name) inside the unzipped APK. If .godot is not removed after opening the project in the editor, the .res files contains the noise textures, but they are absent when exporting without the .godot directory.

This sounds like a duplicate of #66842 or possibly #88187 which have both been fixed in 4.3. We should have a dev4 release ready soon that you can test to confirm

[ygingras]

That's great! I'm looking forward to try the next dev release.

[ygingras]

It's also certainly a dupe of #66842 since disabling binary conversion of resources solves the issue.

The minimal repro project exports with the required material textures on 4.3-dev4. Nice!

Amazing! Thanks for testing again
