ABSOLUTELY! I would be a convert in a blink with water masks. I'm kind of late to this discussion - How well do the masks match with the imagery? Is there an alpha blend? Both FS9 and FSX?

Christian,Go for it.

That part is not done yet. I am just at the stage where I am loading (and caching) the water mask bitmap data.Next step will be interpolation (blurring against the jagged edges) and applying it to the tiles. I think I can get that done today. Then I will post screenies.Christian

Let me know if we can help in some way!

Christian,Will TP6 be compatible with FS9? That is the important question for me.Thanks

I think so. Water masks have been supported in FS9 also. Just not sure whether DXT3 was also an option, but depending on configuration my program will generate either "abrupt" DXT1 alpha masks or as smoothed DXT3 masks.
