into the config.txt may fix that depending on which way Ben did the y axis. Your tank may lean a bit but should still be interactive.
thanks , I already tried it, but it only tilts sideways , not much use.... and a 5 degree tilt would not look all that great either. its possible that his gmax original models will be donated and will be able to be changed , I note one was changed recently on DLS although i cant remember in what way. i don't think it was a reskin. all the URY rolling stock needs mods to the couplings , I asked him if he would do it but he wasn't keen , I guess it was old work and he wanted to do something new. also, the URY side dump cars will not show loads unless manually loaded from interactive tipples.
