Custom vehicle physics bone creation problem

Hi y’all. Dunno if I’m in the right section to present my problem but if it’s the case, apologies. I’ve been having imported custom vehicles bone creation problem. I’m still a rookie but i’ve tried my best to have the basics. I’m working with 3ds max to edit bone orientation as well as for their pivot. When i import them to ue4 i get the following problems

  • vehicle not colliding with landscape when body creation is applied
  • Vehicle moving diagonally when steering
  • Vehicle like floating about some center.
  • Vehicle taking an inclined stance on landscape

presently i’m srsly confused if the problem is in 3ds max around bone weight and weigh table stuffs or if the problem is in ue4. I had already created the basic bp’s for the vehicle to get going but it just wouldn’t
