Rather than start a brand new thread on Invisible Assets, I am posting here:
Do you use invisible assets ? Yes
Triggers, Direction Markers, Trackmarker, Speedboards, Bi-Directional Bell and Horn, Signals ... etc ... etc
All these assets have the tag in their config file: -surveyor only 1 , the 1 means YES,which makes them invisible.
By edit in explorer, and changing the 1, to be a 0, which means NO, the invisible asset now becomes visible.
Why on earth would you want to make an invisible asset, visible ?
For trouble shooting your route, and seeing where to move bell, whistle, speedboards and trackmakers... the tag can always be changed back to -surveyor only 1 at a later date.
Just be sure that you only change the numeral, as you may be changing a built in asset that can't be re-downloaded.
If you mess up the config fle, someone could send the original config file "text" to you, should you ruin anything.
