Well, maybe not.
ntt1010.til reads:
0000002A,1
c:\documents and settings\dan\desktop\terrain set bmps\new folder\ntt1010,TextureName
That's it, the whole text of beach file.
My main interest is in the European tile set. Ntt0002.til lists out looking like a PAC set instead of an evergreen forest, and I would expect two separate sets. One for the PAC and one for the ETO, I'm not sure if that would be right or not, but I can't think of another way to do it.
