This is a program that will allow you erase ALL layers of texture from a specified spot on your route. You have to use the (included) special texture to completely cover the area to 'clean' and then save your route. Once saved, you then open the route for edit in Explorer in Content Manager and then start my program. Point my program to the Edit folder in your Trainz installation folder and locate the .GND file to start the erasing process.
There is a 'readme' file included with the ZIP file so you can look at that before deciding to install the program itself.
NOTE: This program will NOT work with TRS2010 due to file structure changes!!!!!
