I'm currently working on a graphical user interface mod for RUS, and I was planning on keeping things hush-hush until it's finalized (which may take a while as I'm a perfectionist), but I was so pleased with how these armoured cars turned out that I wanted to share them with all of you...
The rest of the mod will consist of more subtle changes, but I may make some more unit portraits in a similar style for the armoured trains. It may look like they took a lot of work but it was actually rather easy to do using layers and filters - I used good quality period photographs, cut out the vehicles, desaturated the image, applied a "cutout" poster style filter, separated the wheels and undercarriage into their own layer, then fiddled with the colour balance/vibrance/contrast etc. to taste, sharpened the edges, resized and then sharpened and retouched as needed.
If you unzip the following archive into your game's main directory, it should replace the files automatically - it is highly recommended that you keep backup copies of the original files!
