Summer Aspen trees contains 190 unique, highly detailed Quaking Aspen tree models. These models cover the entire life cycle of the Aspen tree. Multiple bark textures means that neighboring trees will rarely have the same bark pattern. Included, is 10 placement blueprints that will allow for planting of a random set of trees of a similar age range within a region. The placement blueprints use vertical line-of-sight so they can be placed on sloping terrain.
Tree materials have wind, with user adjustable parameters. Each unique model reacts slightly differently to the wind parameters that are global to the material. The height and width of the tree also contributes to the final wind motion.
