I'm trying to create tree billboards for some custom trees using this tool, http://www.nexusmods.com/skyrim/mods/60733/?tab=4&&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fskyrim%2Fajax%2Fcomments%2F%3Fmod_id%3D60733%26page%3D1%26sort%3DDESC%26pid%3D0%26thread_id%3D2365989&pUp=1

I can capture the images in the CK and then place the BillBoards in C:\Program Files (x86)\Steam\SteamApps\common\Skyrim\Data\textures\terrain\LODGen\.esp Then generate tree lod using TES5LODGen, I receive a warning (or Note) that the files cannot be found. One Tree is found, but there several others that are not. The ex: is for the trees that do not show. But I have placed them in the folder.

I don't know what is wrong. Any Help will be appreciated.
