Collision problems

[Majk369]

Hi everyone,
i was struggling with creating wagons past months... my first wagon however was succesfully working, but it stopped there. since i was creating it by following rw manuals for developers, it was the kind without any bogies (or one, which is the wagon itself). when i tried to make standard two bogie wagon, it all went wrong... i was putting all the stuff into the blueprint editor corretly (as far as i know). but there was always this thing: the wagon seems to have some kind of collision box that i cannot adjust by collision geometry models, nor by changing the collision proportions. so i found out that there might be some problems with physics in the game. on the dev docs they say that you should install nvidia physx debugger and work with it, but that failed too... i could not even connect it with the game. so it still stays a mystery for me...
hope someone will help me....
thanks

NOTE: my pivots in the 3d model should be fine as well
