Thanks for all the help Jim! Really appreciate it! Are you familiar with creating seasonal textures? Or is that just a whole different ball game?

It's a PITA, lol. You could try putting a white layer overtop and set it to "overlay" or "screen" (I can't remember which, do some experimenting). Then maybe add some noise and use your eraser tool to "plow" the roads, etc. What works is sort of a crap shoot, every peice of imagery is different so you just have to experiment. You can copy and convert some of your landclass textures to 24 or 32 bit so you can get them into PhotoShop which makes matching a bit easier.

I've done winter textures just by simply using the color select tool in Photoshop. I have saved my various colors(greens and browns mostly) in whatever adobe calls the file now(can't remember) so I can re-use for every summer texture I create. With that "color select" file saved, I can then run a batch with all my summer textures. I run them through a color select "action", replace those selected colors with white, desaturate the image and then save them off in a winter folder or something. Then, I compile the bgls with summer, winter and any masks that I have. It actually looks really awesome, IMO. Here's a sample...

 

By the way, I had to drop the resolution and change to jpg so this looks no where near as good as it does as the original BMP and in FSX. So, take that into consideration.

That does look awesome Kevin!
