This is why I'm only shuffling Hitech's bitmap files to create my palette. The two unused rock texture bitmaps are all I ever wanted.
By the way, even when I placed in the terrset00\texsrc folder only the bitmaps referenced by the atlas files. The first time I did a build, ALL of the bitmaps were placed in the terrset00\texsrc folder from the 508 and 1016 folders automatically.
I didn't want to do anything that made my work questionable for MA use. Now I've got rock tiles made by Waffle that work for my Svalbard style theme. And there is no sand on Svalbard, beaches made of rocks the size of your fist and the same for all the talus slopes and erosion skirts around the base of all the mountains and canyons. The real island is in the arctic circle so only has grass. Mine is down offshore from Norway about midway down the country so it can have trees while looking like Svalbard.
Just realized I have to place a few islands in that fjord that runs up to the tank town so some genius dosen't park a task group on top of it and kill all the GVing fun. When I mapped out the feilds, I drew a 1.5 sector diameter ring around the tank town and didn't place any feilds inside of that. Not much but many players won't fly 1.5 sectors to try and find GV's to harass.
