Path Array Pro – A Flexible Tool for Creating Path Arrays in 3ds Max. Path Array Pro is a MaxScript tool for 3ds Max designed for more flexible object distribution along a spline. Instead of simply repeating objects along a path, Path Array Pro gives the artist additional control over scale, randomization, orientation, distance between objects, and real-time array updating. The tool can be used in architectural visualization for decorative elements, plants, lamps, furniture, rocks, cables, and other repeating objects.
