A request was made elsewhere concerning Imagetool batch processing and help. There are examples in the FS2004_Terrain_SDK.exe that show how to use some of imagetool's internal functions. If you are interested in these functions, use the following at the DOS (Command) Prompt:C:Imagetool -h It is interesting to note the additions to the latest Imagetool over previous Imagetool versions, even though the version number didn't change. A little QA is in order!W. Sieffert

Hi all.Another function of the new imagetool worth exploring:The lower left pixel color can drive automatic alpha-channel generation. Make it black, then use the tool to convert to 32-bit... now it can generate an alpha, then convert to DXT1.Dick

Howdy,thanks to both of you for the information; I hadn't noticed the differences yet either. To facilitate further discussion, here are screenshots of the help screens of the two versions. Given that the images will disappear from the forum it's probably best to save them on your HD for future reference.Cheers, Holgerhttp://forums.avsim.net/user_files/79908.jpghttp://forums.avsim.net/user_files/79909.jpg
