Stripped classes in animation.rigging package

Hello,
Seems like unity/C#/IL2CPP is stripping some classes in the
com.unity.animation.rigging package when I build to standalone. I have managed stripping level to Low and C++ compiler configuration to Release. I fixed/haxed it by placing some
var overrideTransform = gameObject.GetComponent<UnityEngine.Animations.Rigging.OverrideTransform>(); in my main assembly for the classes that are stripped. The classes that are stripped is:

Code (CSharp):

1. UnityEngine.Animations.Rigging.OverrideTransform
2. UnityEngine.Animations.Rigging.Rig
3. UnityEngine.Animations.Rigging.MultiParentConstraint
4. UnityEngine.Animations.Rigging.MultiReferentialConstraint
5. UnityEngine.Animations.Rigging.BoneRenderer
6. UnityEngine.Animations.Rigging.RigBuilder
7. UnityEngine.Animations.Rigging.RigTransform
8. UnityEngine.Animations.Rigging.TwoBoneIKConstraint

Would be nice if they get slapped with a [Preserve] attribute maybe

Regards

 

forgot to say that my unity version is 2019.4.6f1 and animation.rigging is preview 0.2.7

 

Will see if I can repro it in a smaller project.
Though I have all models and animation stuff in assetbundles. So that could be why it stripps the classes

 

I managed to repro it.
I have the animations in a AssetBundle and my PlayerSettings have:
Scripting Backend: IL2CPP
Api Compatability Level: .NET 4.x
C++ Compiler Configuration: Release
Managed Stripping Level: Low

I got the repro when I switched to ".NET 4.x" I had already made so that it loads the model via AssetBundles.
When I switch to ".NET Standard 2.0" it starts to work again. I guess it is different compilers so they might stripp differently?

 

I have now uploaded a bug report: 1272602
I remade the project and noticed that it was bugged on both .NET 4.x and .NET Standard 2.0 in the new project.

 

I guess that it is most likely an assetbundle problem right? Hard for the compiler to find dependencies in already built bundles maybe?

 

Awesome!
Good to know that my bug report is helping

 

For us, animation Rigging
- works in the Editor (both when loading a Scene directly, and when loading a prefab via AssetBundle)
- works on Android/iOS Devices the App when loaded directly from a Scene
- does not work on Android/iOS Devices when Loaded via AssetBundle.
We get the following:

Could this be related?
I just found the issue in the Tracker - will try the suggested solution there...
https://issuetracker.unity3d.com/is...ging-scripts-when-building-with-asset-bundles

However: The info in this Issue is not exactly very detailed.
So if i understand correctly everyone who wants to use the animation-rigging package with AssetBundles will have to somehow fiddle with the Manifest maually and Add File references there?
Sounds rather like monkeypatching than a real solution to me - so maybe I'm missing the bigger picture, or misunderstood the solution?

 

Any solution for this? i'm having this issue, should i use addressables?
