Re: [Interest] [Qt3D] Assimp OBJ importer can not import a file with 500MB size
Why then QMesh can import the geometry data even if it is 1GB file ?
Thank you.

sadly the app for 3D printing, which they use obj and stl formats the most. Thanks.

Assimp 4.1, integrated in qt 5.11.1, already added stream reading of
obj files, and is the most recent version. You will have to raise an
issue to assimp IMO, then if it can be improved, rebuild qt with that
new assimp version

[Interest] [Qt3D] Assimp OBJ importer can not import a file with 500MB size
Hi,
As the title says, i can not import a *500MB* obj file *( 6 million
vertices and 11 million faces )* using QSceneloader.
getting this msg :
Qt3D.AssimpImporter: Assimp scene import failed OBJ: Too many vertices,
would run out of memory
Qt3D.Renderer.SceneLoaders: class Qt3DCore::QEntity *__cdecl
Qt3DRender::Render::LoadSceneJob::tryLoadScene(class
Qt3DRender::Render::Scene *,enum Qt3DRender::QSceneLoader::Status &,const
class QStringList &,const class std::function &) Failed to import
QUrl("file:///C:/Users/USER/Downloads/a.obj") with errors ("OBJ: Too many
vertices, would run out of memory")
Thanks in advance.
