Can anyone explain why the fuel tanks were missing after the SU5 update? Before that, everything worked fine and displayed. I have written my own logic of the fuel system and now nothing works. What can be wrong?
We need more information.
What file are you editing?
Are you editing the Flight_model.cfg file of a package or in the original airplane?
Is the new Flight_Model.cfg file in the layout.json of the package?
Have you read the SDK regarding this, maybe something changed?
There are so many things to check here. Without access to your development environment, how can we answer your question?
