If your problem is these weird cubes that appear, it must be an option of the DEV mod that has been activated for debugging purposes. Perhaps an inadvertent click.
In any case, what I notice with pleasure is that now the effects are applied to the balloons at the tip of wings which I had not been able to achieve 3 years ago with the PBY because amphibians were not supported at that time.
What adds me still u little work to review my XML codes and adapt to this aspect of the SDK. However, the effects seem very promising
