I feel you. Scripting multi-axis is veeery time consuming. But you really should try setting up MFP to use the additional axis bound to the one axis you’re actually using: https://discuss.eroscripts.com/t/multifunplayer-transform-single-axis-scripts-into-multi-axis/84269
I mean, of course it’s not the same as dedicated scripts and some might dislike the “lost realism” but you can tweak it however you like and it’s actually pretty neat.
