Patty is a kit for MODO that helps you to create patterns procedurally. Patty consists of a collection of new channel modifiers for manipulating patterns and strings. They can be used to create procedural models which are more robust to change. It can also be used to create interesting animation effects. If you use pattern selections a lot, this is the kit for you. The kit is compatible with MODO 11 and above (the Pattern:FromArray modifier is supported from MODO 16 and above). It is written in Python and so is platform independent.
