Stuff looks good in game. I'm going to hold off on including the parasol caps though, and it would be nice if they were paler to look closer to the originals. The main reason I am holding off on them though is because you didn't send me caps for all of the various different parasol trees, only the big ones.
The rest of the textures you sent me will be in the next update which I am hoping to get out by tonight.
Definitely drag and drop, there is stuff in these packs that was never in the guide before I got into doing this. Don't forget to grab UC: Armory as well, it's got a lot of nice things my guide didn't used to have, too.
Upgrading to the UC packs from older versions of my guide should be safe and clean in general.
If there is anything in this pack KINGPIX would want to use but isn't using already, he would only need to get permission to use it from the original authors on his own. I can't give him permission myself, but if I could I would.
