Hi, For a long time now I've been using ballistic submodels for trajectory markers.
When using the trajectory markers, a simple inverted 'T' two line object is created at the aircraft position once per second, aligned with the aircraft roll and pitch axis. The submodels have no weight, 0 buoyancy and are unaffected by wind, so once created they remain in place and provide a representation of the aircraft's flight trajectory. I just tried using them, having not used them for a while, and found that about half of the submodel instances are rolling over and spinning around. The problem seems to be random and about 50-50, with no obvious pattern between instances that behave properly and those that rotate and spin. As they're all created from the same config I'm at a bit of a loss as to how to fix it. I noticed that the README.submodels doc doesn't include a definition for the <aero-stabilised> tag but it is used in one of the examples. I've always used this tag as a bool i.e. 'true/false', like the <wind> tag, but in the examples the <aero-stablised> value is '0' whereas the <wind> tag values are either 'true' or 'false'. Is '0' used in <aero-stabilised> to represent a bool or is it now a numeric value?
