5 years ago Another example with a stop sign model, Studio crashes cold with the same Filament Precondition Panic (material expected 4 but received 1). Command line verbose compilation shows no error whatsoever:

The stop sign object The caution sign object
I think the Android Studio Crash might not be because of the conversion but when it tries to open the sfb file and visualize it for me? When I completed some code labs the sfb file was never displayed graphically but just as binary sequence.

I thought it gonna be easy to try to place some simple stop sign models onto an AR scene. I downloaded several stop sign models and a caution sign model from
polyand all of them crashes Android Studio when I try to convert theobj(+mtl+png) tosfa+sfb.I see that
Google(orJetBrains) receives a Crashlytics report about the crash, but I could gather somestderrinfo when I started the Studio from command line (and then you see thestderr):The
sfaandsfbfiles are created though.If I compile the file manually:
There's no error message at all.
After that when I try either the Studio compiled version of sfb or the command line compiled one I get the same runtime error along with an application crash:
I'm using Linux operating system
compileSdkVersion 28minSdkVersion 24targetSdkVersion 28Android Studio3.5Google Sceneform Tools (Beta)1.12.0My application would be a simple concept but I'm kond of stuck because all models I tried so far does this. On the other hand the Sceneform Introduction codelab ran fine on my machine.
I'm giving more details below.
