.STK File Extension

Pivot Animator is a Windows program that allows you to create stick figure-based animations. Each animation can include any number of stick figure characters or objects. These stick figures are saved as STK files.

Animator includes many default STK files, which are stored in the following directory:

This PC/​Documents/​Pivot Animator v#/​Figures

You can create your own STK files or edit Animator's default STK files using the program's Figure Builder. To open Figure Builder, select File → Create Figure Type from Pivot Animator's menu bar.

Each STK figure includes a main handle, denoted by an orange dot, and additional movable segments, the joints of which are denoted by blue dots. STK figures can also be comprised of sprites , instead of line-based segments.

To open a .stk file, you need compatible software that supports this file format.
