Hi,
could you file a JIRA with a test case please? Which version of Qt is
this with?
Thanks,
Sean

Hi,
I have entities that should be created and deleted at runtime. Entity
have only material and mesh component. Material is QDiffuseMapMaterial
with QTextureImage.
When entities begin to add and delete from scene, sometimes
application crashes with this assert:
qt_assert: ASSERT: "img != nullptr" in file
../../include/Qt3DRender/5.8.0/Qt3DRender/private/../../../../../src/render/texture/apitexturemanager_p.h,
line 286
<x-msg://4/src/render/texture/apitexturemanager_p.h,%20line%20286>
But unfortunately I can’t find why it happenes. I’m adding the entity
this way:
QEntity*visibleObject=newQEntity();
QDiffuseMapMaterial*material=newQDiffuseMapMaterial();
QTextureImage*diffuseTextureImage=newQTextureImage();
diffuseTextureImage->setSource(QUrl("qrc:/resources/tile.png"));
material->diffuse()->addTextureImage(diffuseTextureImage);
material->setShininess(0.1);
visibleObject->addComponent(material);
//setmesh
QPlaneMesh*mesh=newQPlaneMesh();
mesh->setWidth(1.0/2);
mesh->setHeight(1.0/2);
visibleObject->addComponent(mesh);
visibleObject->setParent(_rootEntity);
And delete just like this:
deletevisibleObject;
_rootEntity is root entity defined in cpp code. Scene defined in QML file using
Scene3D:
Scene3D{
id:scene
anchors.fill:parent
aspects:["render","logic","input"]
entity:rootEntity
}
And _rootEntity passed like this:
context->setContextProperty("rootEntity",_rootEntity);
If it is necessary I can prepare simple example that reproduce issue.
Thanks.
