Hi, You need to run the simulation in synchrounous mode to make sure all the data is generated and retrieved between simulation steps. This is explained in the documentation (https://carla.readthedocs.io/en/0.9.14/adv_synchrony_timestep/) and a complete example is given in sensor_synchronization.py. Here's the relevant part of the documentation "Using synchronous mode
The synchronous mode becomes specially relevant with slow client applications, and when synchrony between different elements, such as sensors, is needed. If the client is too slow and the server does not wait, there will be an overflow of information. The client will not be able to manage everything, and it will be lost or mixed. On a similar tune, with many sensors and asynchrony, it would be impossible to know if all the sensors are using data from the same moment in the simulation.
The following fragment of code extends the previous one. The client creates a camera sensor, stores the image data of the current step in a queue, and ticks the server after retrieving it from the queue. A more complex example regarding several sensors can be found here.
settings = world.get_settings()
settings.synchronous_mode = True
world.apply_settings(settings)
camera = world.spawn_actor(blueprint, transform)
image_queue = queue.Queue()
camera.listen(image_queue.put)
while True:
world.tick()
image = image_queue.get()
"
Great! Thanks @p-testolina

Hi All,
Unfortunately I can't get all frames from my CARLA, only if I set lower resolution (320x240) I can successfully get all of them. My frames list looks like:

... by running tutorial.py from examples or any other flow with _image.save_todiskSetup: CARLA version: 0.9.13/12 Platform/OS: ubuntu 20.04 RAM: 64Gb NVIDIA-SMI 525.60.13 Driver Version: 525.60.13 CUDA Version: 12.0
Any idea? Thanks
