Thanks for reporting the pixelation and brightness issue
About the seams its not much i can do about it. Perfect UV-mapping is really only possible on trees generated completely by a tree generator, if you then make changes to it (which i like doing) you mess it up.. I can choose between really drawn out textures or seams that you only really notice if you examine the trees very closely (too closely!
)
I wish Bethesda would have stuck flora_tree_ai_06 down the same amount on all trees, sometimes the roots are too visible (looks bad) sometimes the tree is stuck too deep (also ugly and makes it look like a telephone pole more than a tree). I might end up with a .esp where i fix things like that heh, for now it's not much i can do, i changed the z axis to a value that seems to look decent on most trees.
DarkDiva: it's been called "Vurt's Ascadian Isels Mod" for the 2 latest versions. I'll update it on the PES main page for the mod too..
