I have put together a kit to make enamel station signs a bit easier.. but think you are gonna need a tutorial thanks to my wierd way of thinking so here goes.

Outline of technique
We use an excel spreadsheet template to produce a texture on your clipboard.
This is then pasted into your Paint program and saved.
Convert to ACE format a place in the required "Source" location
Open the relevant Blueprint in the Editor, Edit a template blueprint and export
View and place in game
Open The Supplied Excel Spreadsheet
Font should be Gil Sans MT , however not everybodys excel will have this.. use MS Sans Seriff

The Top row has a set of Icon buttons to select which Region / Colour you require
Choose the Sign type you wish to make and edit the text in the Black and Orange Boxes

It should Preview on screen

Click the relevant Button to Copy to Your Clipboard

Thats it for the excel bit... cya in part two
