Vehicle wheel collision offset.
I am working on project which includes usage of vehicles. Since the beginning I am experiencing problem with vehicle setup. I have identified this issue to be caused by offset of wheel collision meshes which are assigned to objects of type VehicleWheel. Using
In UE4.10 i have set up WheeledVehicle BP, It's wheels (class, bone names, no offsets). Bone names match those in Skeletal Mesh. Vehicle does work normally, wheels rotate and steer. Same blueprint setup works for different Skeletal Meshes, where collision meshes match the bone positions.
I am using custom mesh which i downloaded and modified in 3DS Max 2013 (Student version). I believe this to be the cause of problems. Since I am beginner in 3D modeling i might have made some mistakes regarding transforms etc.
Structure My model has no bones, i have vehicle chassis (single object) as parent of 4 wheels (5 objects total).
Scale Since i did scaling of the objects i applied xform reset on all objects as it was repeatedly mentioned in answers provided by community, however it didn't resolve anything (all objects have now 100 scale).
Pivots Chassis pivot point is set to (0, 0, 0). Wheels have their pivot in their center.
Export and Import I used several export/Import options. Did not help.
I have spent several days trying to figure this out, with no luck. Feeling desperate. Thanks for your help in advance VB

You must use Reset XForm in 3DS MAX before export your model. Unparent Wheels. Then select Base and Wheels and apply Reset XForm. Convert all meshes in an Editable Mesh. Parent the wheels to the base. Export the model to FBX. In export dialog, change FBX version to 2014/2015.
Import model to UE4.

HI, thanks for your response. I believe i already did XForm reset and converted to Editable Mesh. Nevertheless, i tried it again and there were no improvements. It is possible I am doing it wrong. What import options did you use? Could you send your FBX, which you used in picture above? I think it would help me a lot. Thanks for your time VB.

So the solution you are using is just to manually offset the weel in the vehicle movement component? If yes did you get any bug after using that trick as a solution? Thank you, Mike
