help "<b>Distort Tracks Gizmo</b>\n\n<b>About</b>:\nThis gizmo reformats and/or distorts tracking data based on a uv distortion map input. When you are working with CG elements in your comp that are undistorted and padded resolution, sometimes it is useful to reconcile tracking data from a 3d position through a camera into screen space. This data can then be used to do stuff in 2d: track in lens flares, matchmove roto or splinewarps, etc. The problem is that when this tracking data comes back from our padded undistorted 3d scene into distorted, unpadded resolution comp land, it doesn't line up. \n\n<b>Instructions</b>:\n1. Connect the UV input to a uv distortion map and set the channel that holds it, (for example, a LensDistortion node set to output type Displacement, outputting a UV distortion map into the forward.u and forward.v channels)\n2. Set the padded resolution format and the destination format: Padded resolution is the ov

Bake Roto is a python script that will bake an arbitrary control vertex on a Nuke Rotopaint shape or stroke into position data. Baking nearly instantaneous, and takes into account transforms for shapes parented under layers that have animations or expression links. The idea for this was based on <a href="http://www.borgo.tv/">Magno Borgo</a>'s BakeRotoShapesToTrackers script.
http://www.nukepedia.com/python/misc/bakerotoshapestotrackers/

Usage:
Select a Roto or RotoPaint node and run the script. Don't forget to turn on the "toolbar label points" button to see the cv numbers.

Example Installation:
Add code to your menu.py to add the script to a menu.
import bake_roto

## LINK TOOLS
	Utility functions for creating linked nodes. This script can create roto linked to trackers, 
	transform linked to trackers, or cameras linked to each other, or held on a projection frame. 

Installation:
Put link_tools.py somewhere in your nuke path.
You can add the script as commands to your Nodes panel. This code creates a custom menu entry called "Scripts".
