Car editing in Blender

Hi, i am playing around with car editing and i have a problem, after importing .dae, it seems that all parts for this specific vehicle are accumulated on each other, is there some way to delete them so it will look normal?

 

That is normal, that's just how making assetts for in-game vehicles works. If you want to hide individual parts, you need to left click on one of them & press H to hide (or Alt + H to unhide all at once) or click the little eye icon on the right side of the screen after each part name

 

Thanks
