I adapted the part.fcg shares configuration files by modifying the "node definitions." This is the "Up Y" that must sometimes change the sign. For example Buran shuttle Part Buran_avionicsection : node_stack_bottom = 0.0, -0.4464045, 0.0, 0.0, -1.0, 0.0,2 Part Buran_cargosection_door : node_stack_door = 0.0, -3.0, 0.0, 0.0, -1.0, 0.0,2 Part Buran_cargosection1 : node_stack_top = 0.0, 3.137035, -0.4077612, 0.0, -1.0, 0.0,2 node_stack_bottom = 0.0, -2.774646, -0.4077612, 0.0, -1.0, 0.0,2 Part Buran_cargosection2 : node_stack_bottom = 0.0, -2.827363, -0.4077612, 0.0, -1.0, 0.0,2 Part Buran_jet_engine : node_stack_jet = 0.0, 0.222462, -3, 0.0, -1.0, 0.0,2 Part Buran_LWsection node_attach = 1.267047, 0.0, 0.0, -1.0, 0.0, 0.0 node_stack_side = 1.267047, 0.0, 0.0, 0.0, -1.0, 0.0, 2 Part Buran_rcssection : node_stack_bottom = 0.0, -0.9800719, 0.0, 0.0, -1.0, 0.0,2 Part Buran_RWsection : node_stack_side = -1.267047, 0.0, 0.0, 0.0, -1.0, 0.0, 2 I have not been able to adapt and share Buran_tailsection Buran_tailcontrol replaced by Squad \ Parts \ Aero \ shuttleWings No way to adapt the Romfarer_RoboticArmBuran either I did the same for the elements of the Soyuz, Progress, Dragon, Cygnus, ATV and the ISS parts.
