Simple Collision Box issue in Blueprints

Can anyone Help? I added a simple “Collision Box” to the Sedan blueprint, so I could detect if a player is standing near a door. But the collision box is causing the car to lean to one side like there is some kind of force, mass, or collision pulling/pushing the car mesh (root component) down to one side.

It is something to do with collision because it only happens when collision is enabled on the “Collision Box”. Here are my settings for the “Collision Box”:

  • Generate Overlap Events = True
  • Collision Enabled = “No Physics Collision”
  • Object Type = “World Dynamic”
  • Collision Responses = Everything to Overlap

This behavior does not happen in v4.7.6, but it does happen in v4.8.1. What has changed?

In v4.8.1 if I take the Mesh Component (root component) and attach a “scene component” to it, then attach the “collision box” to the “scene component” the effect of force, mass, or collision pulling/pushing the car mesh (root component) does not happen any more. Have I fixed the issue or just covered it up?

Could some please help me understand what is happening, the more detail the better please?

I have the exactly same question. I make it works attaching the box to a camera I am using but would to know exactly how it works and the best way to do this.
Thanks.
