If you were wondering where the replacement radars went I have got sidetracked slightly by something else.
I am almost finished with a scrolling map asset, just polishing the script a bit with lots of comments and producing a PDF tutorial explaining how to generated map tiles from your own creations.
Hopefully the radars will be finished in the next couple of weeks, having a bit of trouble with my art department (he is always out with his GF, slacker).
Been there, done that, got all the T-Shirts!
