Clay Studio Pro uses spherical, elliptical and spline shapes from which to construct your models. This program features the primitive type called the Clay Spline that allows the user the ability to quickly and efficiently build complex structures such as body muscle and smooth fluent organic curves and shapes.

Clay Studio Pro builds on the interactive foundation laid by Clay Studio, and adds Clay Splines. Clay Splines allow you to draw out 2D and 3D splines that essentially have the Clay Spheres strung out along their length. Modeling sophisticated creatures has never been easier. Clay Studio Pro also converts standard 3ds Max splines into Clay Splines as well. Plus with the newly enhanced Sticky Mapping algorithm, you can assign individual mapping coordinates to two Clay Splines and when they merge they retain their original mapping.
Advanced features include sophisticated grouping controls for branched models, cube edging so you can work with cube and diamond Clay Sphere primitives (just like Clay Studio) and negative influence fields so Clay primitives can punch holes in one another. New global adjustments also let you modify the parameters of groups of selected Clay Spheres or Splines simultaneously. Of course, it’s completely compatible with Clay Studio so users can transfer files transparently. Clay Studio Pro is an industry standard.
