I've no idea if it will work with A:TW but one must assume it is the same principle; I do not have the game yet as my Eras pack has not yet arrived. Still, games are but a distraction to the serious modder ;)

Teleklos, I'm afraid I did not factor the palms in simply because they failed the first test of actually working once I had copied over the files to a new installation of bi (with the rest of the build). Leaving them in was causing any battle on the strat map or CB to load up a little and then hang and freeze. I was having to use CTR+ALT+DEL to exit. I copied over all the files (inc. the db one and even messed around with rwms generated from the original), but nothing worked and I had to restore a vanilla db file and veg file which seemed to do the trick. I think the sprites are still in so it may give the appearance of palm forests until you get too close and they turn into deciduous trees ;)

I do want them in, but not at the cost of messing up my build at present. I will probably make them an item for a not-too-distant patch. A quick look at the files does not hold out much hope for repathing, so you might want to try copying the entire file set (and related elements such as cas and dds.tga files) into the mod folder.
