it is possible to make filters that read the rgb's convert to greyscale by averaging the rgb's, and rounding the colors to the nearest 255, effectively making 2 colors - black & white. Not sure how to do this on blitz fast enough though :( Half-life 2 did it, so it's possible :P

Or you can make all the textures on the models black and white, however you prefer.

I do believe that video has an effect on it or something to make it appear black and white like that. I recognize some of the scenes from what IL-2 Sturmovik is like, kinda.

I'm guessing this is pretty slow, but...

Use the RGB to HSB to RGB converter in the code archives to change the Saturation to 0, making the color greyscale :)
