I control the EXTERNAL POWER ON from APU GENERATOR SWITCH, the APU GENERATOR SWITCH controled by power bus condition aircraft parking, a invisible APU working states (the only way I know to simulating GPU from FSX) and electical requirments from radio avionics/engine start/igition switchs.
so if using MiG-15`s old GPU cart or even fuel truck, tolly tug, the whole russian ground service objects pack to replace (I think override temperary better, if users want to make none russian vehicle appear on a civil airport?) , I need to build service pack and desgin logics for MiG with russian vehicle, other aircraft call stock ones. and not add too much polygons and complex for aircraft`s main GLTF models.
The main limite is my new computer has low performence with a 4GB gtx 1650 videocard, it can handle models not exceed 60000 polygons (no 4K texture, I am using 2048x2048 pix maxium) in 3dsmax smoothly, the MiG-15 current near 59000 polygons.
