Camera frames not showing up

[eds89]

Hello,

When I load CARLA as a standalone game (non-server), the associated camera frames are not showing up. I can only see them when I launch CARLA as server and connect to it via either Python scripts. It is unclear to me if I should expect seeing the frames for each of the cameras defined in the .ini file.

I'm loading CARLA via the following command line.

CarlaUE4.exe  -carla-settings=CarlaSettings.ini -windowed -ResX=800 -ResY=600

And, my current settings file can be found below. Comments were removed.

Hello, Apparently, the settings file isn't being loaded up, according to the log file:

LogInit: Command line: -windowed -carla-settings=

Hi @eds89,

No, you shouldn't. The server does only display the main camera only for debug purposes.

The reason that you see the other cameras in the client side is because it is coded in the manual_control.py to display these frames in that certain position in the screen.

So, isn't there a way to see what each camera is recording while the car runs through the level?

@eds89,

If you mean in the server, it is not implemented because this is not a necessary feature for us. Anyway, as it is a post processing material, you can attach it to a certain camera to visualize it.

It's up to you use the Unreal Engine to render different cameras in different frames on a single buffer.

Regards.

Hello, That's ok. I've managed to change the python code to load settings dynamically (on manual_driving.py). I'm now looking for instructions on how to save recorded images as png files.

Hi @eds89,

Sorry for the late response. Please, make sure you have took a look at the provided python examples before asking.

In the client_example.py you can find an example of saving the images:

Good luck :)
