lifting all the tracks in project? help needed

[zuikki1]

Is there anyway to lift all the tracks and terrain + fneces etc. all together inside the btb-.. I started my project accidently too low and now I can´t get under my track in btb or not even to the surface., Lifting the tracks one by one seems frustrating with terrain adjusting and track "welding" together...

You can lift the tracks one by one. You can lift all the terrain and objects together. But, as far as I know, you cannot lift everything at once.

Yeah, I made the same mistake (sigh).

I revised my track-building process so that I now add low-poly placeholder terrain to the whole track (using the add-to-whole track feature) so I can get a feel for the elevations by driving it. Doublecheck and triplecheck and become certain that I like the track elevations. Once the elevations are done, I throw that terrain away and make the real terrain with more polygons.
