Tracks Delete object in 3DSimEd

[azizulsyaiful]

I have a track which I want to remove some barriers in it to enable the track layout to be fully used.

I only have the .kn5 file of the track therefore Im trying to use the 3DSimEd to edit the track. I have tried editing the object from the object instance, render=false & collision=false, however, this only make the object transparent when i play it in AC and still collide cannot move through the object.

I would like to delete the object entirely from the track? Anyone know how to do it aince I’ve been googling to find no answer.
