Some objects do not appear.
I load a 3ds model using qt3d. firstly everything is ok, but when i rotate the model, some objects do not appear.
It would help if you provide some working example code and a model that reproduce the issue. Also, what possible causes have you already checked?
I uploaded a video which helps me to explain my issue.
I am using the same code in the penguin example just changed the 3ds file name.
