In this section, you will find documentation for TheParametricLibrary,

an exclusive range of ready-to-use high-quality procedural assets only available from iToo Software. All the libraries are designed to take full advantage of the unique features of RailClone Pro, the powerful parametric modelling plugin for 3ds Max.

Our ready-to-use assets take the hard work out of parametric design, allowing you to use advanced RailClone Pro features in minutes rather than hours. If you're able to create a spline and edit some parameters, then you already know everything you need to create a model that can be customised to create thousands of variations.

What's new?

Background Buildings Vol.1

Background Buildings Volume 1 includes thirteen individual high-quality parametric towers, each with fully editable footprints, height, materials, and more. For large areas, a time-saving all-in-one preset is included to quickly create a grid of buildings that can even be made to follow a path.

Background Buildings Vol.2

Background Buildings Volume 2 adds 13 more towers to our popular range or parametric assets. Building footprints can be drawn using closed splines which can be straight, curved, or a combination of the two. 1000s of material variations are possible as well as illuminated interiors for night renders, and much more.


TheParametricLibrary is compatible with the following:

  • 3DS Max 2014 and above
  • RailClone Pro 4.3 and above. V-Ray. Corona Renderer. Arnold
