Physics fixing model collider in 3ds max help

[ensiv]

so I'm trying to make the collider on this bike mod smaller but when ever I try it either doesn't change the collider at all or kseditor comes back with "error found scaling on node rootnode" anyone know how to fix it?

You can't scale it as an object, you have to scale the mesh geometry directly. In max you use "reset xform" to correct this.
