Is Crunch Compression supported for Android in Cloud Build?

I just went through the pain of manually configuring lots of texture assets to use Crunch compression, and now in Cloud Build I get a ton of these warnings:

RGB Compressed ETC UNorm format is not supported, decompressing texture

I've searched and googled and I can't find an explanation of what "UNorm" is. I can only assume it relates to having turned on Crunch.

Anyways, it defeats the purpose of compressing all these assets if the Build process then decompresses them. What do I do?

Settings are pretty much the default:
Max size 2048
Resize Algorithm: mitchell
Format: Automatic
Compression: Normal Quality
Use Crunch: checked on for some assets

What should ETC2 fallback be set to?

 

Still waiting for some input:

• Windows build size: 84mb
• WebGL: 80mb
• Android: 207 mb

Something is seriously wrong here.

Notes on currently used settings:

• I put the bulk of 2D sprite textures into atlases and compressed using crunch.
• In Build settings, Android compression is set to ETC2
• ETC2 fallback is set to 32-bit, half-resolution.
• Compression: Default

Through all this, I got Windows and WebGL builds down to under 100mb, while Android is still stuck at over 200mb.

 

Got my answer here: https://forum.unity.com/threads/texture-compression-override-in-android-build-settings.273711/

Cloud Build ignores the Build Settings' texture compression setting.

This was also an invaluable read as far as understanding texture compression options, formats and best practices: https://gametorrahod.com/dealing-with-ios-android-texture-in-2019/

 

@LilGames do you have any insight into my issue?

I'm curious as to what settings you use to get textures to show on the Android via Unity Cloud Build.

Thanks!

 

Found my problem. It was a problem with the model. It was a Blender file which UCB doesn't support.

 

As you mentioned, your problem was not with texture settings, but to answer the question, in case others come here looking for answers related to texture compression and crunch:

In Platform-specific texture import override settings, I set Android to use "RGBA Crunched ETC2". This covers most devices. And for devices that might not support ETC2, we added additional code for Android fallbacks rather than relying on the single fallback in the Build settings. We added this to a prebuild class:

Code (CSharp):

1. #if UNITY_ANDROID
2.         EditorUserBuildSettings.androidBuildSubtarget = MobileTextureSubtarget.ETC2;
3. #if HIGH_QUALITY_32
4.         EditorUserBuildSettings.androidETC2Fallback = AndroidETC2Fallback.Quality32Bit;
5. #else
6.         EditorUserBuildSettings.androidETC2Fallback = AndroidETC2Fallback.Quality16Bit;
7. #endif
8. #endif
