I figured out how to change the master-file...trial and error
however I'm still having a missing detail problem:
I'm looking in the 'graphic' folder and all the default folders have 'rail' within 'road'
sub-folder. The only difference is that the background color : pink instead of white.
when I pick road in editor the 'rail' choice is not there. (??)
Also can I edit the 'plain' scheme with a paint program and save ?
If you don't have the rail+road and road draw options available, i think you may have made an error while changing the masterfile. It should have made it possible. There is a "manual" solution, but it requires some work, and frankly it is easier to change the masterfile.
Perhaps if you take a screenshot of the Setng submenu and of the road submenu, i could help.
As for editting. Do not edit what is already made as part of the install package. Instead make a new folder, under graphics and put your stuff there. Then when you look at the land submenu, and the individual terrains, change what they use.
The reason for this is threefold.
Firstly, if you make changes to the default installed graphics, and save it where it is, then everybody, in every mod, that is built on those graphics will see the change. They will in other words, get it even if they don't want it.
Secondly changes done to the installed graphics, may not show up, in the ATZIP, that is the most easy way to package a new scenario/mod.
Thirdly every time you get an update from Matrix/Vic then it might overwrite your work.
So, better make a new folder, that your scenario uses.
