This plugin replaces most of Ascadian Isles's (not only, these plants may be found in other regions too) plant meshes with smoother and high-poly versions, along with correct collisions. Included are also optimized vanilla meshes, which look like original, but have a lower polycount and correct collisions. These can be found in the directory 'lowpoly'.
