Hi, I wonder if one could tell me the secret to correctly swapping couplers on locomotives? I want to swap the inaccurate freight/type E knuckle coupler models on some US passenger locos to the more prototypical type F coupler model, however each time I've tried I've noticed that the coupler appears reversed when uncoupled but the correct orientation when coupled. How do I adjust the rotation on the uncoupled coupler? I've tried examing the coupler bin files but to no avail. I tried using the type F coupler models featured in the UTS F40 EP and TRS P42 EP but both render reversed, meanwhile I tried using the tightlock model from the APW class 456 and the coupler renders in the correct orientation while uncoupled, but the colour and scale of that coupler model is too small/inaccurate to use.
You need to edit the loco's engine.bin, there's 4x4 matrices which define the translation and rotation of the attached couplers.
