two questions: since it's now esp-based, is it still possible to run it with the small tree version?. these are the only ones my compi can handle.
The bigger version does not have more polygons, the size has nothing to do with how it performs
The new .esp based version does have a few trees that i've added a few things to, but nothing big. In fact, most of the trees are cleaned up from polys compared to when i did the small size version which is now really outdated.
2nd: am i allowed to translate it for the german community since it has a (nearly) final version?
Sure, as long as no one distributes my work as their own, there's no problem spreading it or translating it or even using it for your own mods.
