SceneView
Crash on closing SceneView with child node
I have a view that shows a model:
val engine = rememberEngine()
val modelLoader = rememberModelLoader(engine)
val materialLoader = rememberMaterialLoader(engine)
Scene(
modifier = Modifier
.fillMaxSize(),
engine = engine,
modelLoader = modelLoader,
view = rememberView(engine) {
SceneView.createView(engine).apply {
setShadowingEnabled(true)
ambientOcclusionOptions.enabled = true
}
},
childNodes = rememberNodes {
add(
element = ModelNode(
modelInstance = modelLoader.createModelInstance(R.raw.part),
scaleToUnits = 0.5f,
centerOrigin = Position(x = 0.0f, y = -0.5f, z = 0.0f)
).apply {
rotation = Rotation(y = -45f)
renderableNodes.forEach { node ->
node.setMaterialInstances(
materialInstance = materialLoader.createColorInstance(Color.Gray)
)
}
}
)
},
environment = rememberEnvironment(engine) {
SceneView.createEnvironment(
engine = engine,
skybox = Skybox.Builder()
.color(colorOf(rgb = 0.2f, a = 1.0f).toFloatArray())
.build(engine)
)
}
)
When leaving, by default, this will crash with (Note that the crash does not happen is there is no childNode):

2024-04-01 16:47:13.108 32172-32172 Sceneview D Engine destroyed
As a workaround, I override the original Scene method to do the following which solves the crash:
onRelease = { sceneView ->
sceneView.childNodes = emptyList()
sceneView.destroy()
}
It appears that there could be a second destroy somewhere that is leading to this crash.
@ThomasGorisse It still exists in v2.2.0 Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
It is fixed for first 2-3 navigations, but then it crashed again.
This needs to be reopened, because even on version v2.2.1, it's still present:

I'm still compelled to keep my workaround present, because it's the only way it works for me.
