I can use Photoshop and Gimp, as I have both, but I have a hard time getting it to look like what I want. Herweh did such an unbelievable job on this. Ok, B2s is Backglass, 2 screens. This will do the same thing that uvp will do, and more. It's basiclly a way to display the scores on the backglass, without the lag, and is customizeable. It works with VPM and originals, ss, and dmd games too. Yes, it supports animations. Essentially here's what you do:
Import you bg, and darken it a bit so the lighting will "pop" more. This is done with a slider.
Add your lights. Stretch and size the light and see in real time what it looks like. Then, if you like, export the illuminated image as I did. Instead of having to code all this in Visual Studio, this is done by the program. You assign the light ID number, and call it in the script. Same with the reels, etc.
Add your script calls. There are stock commands that are used with the light ID.
This is still in the testing phase, I am a tester.
