Which format would be most suited for scenery use ect.? (in view of gmax use)Letats

Only 8-bit, 16-bit and DXT1 formats work with sceneries. I usually try to use 8-bit as much as I can, because it gives you the best framerates. DXT1 is also pretty fast, but textures packed with it usually get blurry. 16 bit (565) gives you the best quality, but the size of the texture file is very large and a large airport made with only 565s could be very hard on framerates. Is usually use 16-bit textures as night textures because 8-bit palette isn't enough for them.

I prefer to use DXT1 or DXT3 textures. These textures give the smallest size, although that can give a little loss in quality. They also seem to be good for the framerates (much better then the old r8 (raw) and bmp textures).The main difference between DXT1 and DXT3 is the size of the alpha channel, DXT1 only allows 1 bit, so for different levels of transparancy and reflections DXT3 is needed.Arno
