Autohedge is a fast, easy way to make hedges that suit your landscaping. It consists of a plugin for V-Ray (3.x or Next) that instantly fills any mesh with a realistic hedge. Tall or short, fat or thin. Make hedges, bushes, shrubberies, or whatever you need. Edit the shape at any time. No more searching through catalogs of pre-made models to find the perfect hedge. There is no limit to the shapes you can make, it automatically populates branches and leaves during rendering using detailed materials made from real photographs. You can change the species, density, messiness, and more at the click of a button. It includes a library of common shapes to get you started quickly and comes with 18 common hedge species.

Autohedge is available for Max 2016 to 2020 and costs $149. A demo version is available here.
