Does anyone know how to implement a two-wheeled vehicle without it falling over?

I’m trying to implement a bike, from blender to UE4. After a lengthy argument with UE4 and blender I’ve finally figured out how to consistently implement four wheeled vehicles. Two wheelers, however, tend to act a little odd and then just fall over. Does anyone know how to implement a bike/motorcycle in such a way that it will stand upright when stationary?

the way i did it in ut2004/ut3/udk and now when i get time in UE4 is to use invisible side wheels (stabilizers / training wheels like on a kids bike) just add a bone on each side, not perfect as the bike won’t lean into the turn but at least it doesn’t fall over

Thanks, Geodav! I saw some of your old stuff in regards to doing this in UDK but wasn’t sure whether the new vehicle system was up to handling this yet. I’ll do this for now and it’ll surely get me out of trouble until I find something that allows a bit of leaning, thanks for the clarification.

Oh, and thanks for all your videos, too. I’ve been learning a lot from those the last few days. :slight_smile:

I’d love to ask, by the way, do you do this in blender? I seem to have a lot of trouble with skeletons/armatures not exporting to FBX properly, even with the “fix” that is floating around the community. If I apply armatures to my vehicle they wind up all compressed/mangled/offset in UE4.

you can always try the latest test build of blender which has a better if not quite perfect fbx export.

just make sure that on import you tick the box TOA…

also on your rig make sure you have applied rotation/scale (ctrl+a) before you start skinning
