ClayTools Japanese User Site
Haruo Kubota (haruo@convexpictures.com)
http://www.claytools.jp/
This site is for ClayTools users in Japan. It provides tutorials, FAQs, and technical information in Japanese. The site's focus is on HapticExtender for 3dsmax, but Maya users can also find info about the ClayTools companion application.

ClayTools Curve Import
Mike Brown
Version 1.0 7-23-05 
Use this macroscript to quickly convert a curve network from ClayTools into a surfaced model in 3ds Max. This macroscript will import an IGES curve network from ClayTools, convert it to an optimized spline network and apply a Surface modifier with a reasonable default tolerance, followed by an Edit Patch modifier. You will likely need to adjust the tolerance and potentially flip the normal of the surface from the Surface modifier rollout. This script will conditionally attempt to use the OptimizeSpline modifier to achieve a more accurate spline approximation of the imported ClayTools curves. By adjusting the view steps from the Surface modifier, you can obtain a smoother tessellation result from the patches. Open the included macroscript in a text editor for installation instructions.
Nurbs 2 Spline Script
Alexander Esppeschit Bicalho (abicalho@origamy.com.br)
http://www.origamy.com.br/english/tools.html
ClayTools curves can be imported into 3dsmax as NURBS via the IGES format. You can use this script to convert the NURBS curves into splines.
Optimize Spline v1.0
Dieter Morgenroth (dieter.morgenroth@web.de)
http://www.maxplugins.de
Use this modifier plugin to reduce a spline network so that the only vertices left are the connection vertices. The Surface modifier or Edit Patch modifier can then be readily applied to produce a surface for the entire network. Hint: It is best to first convert all vertices to corner vertices before applying the Optimize Spline modifier.
Conform modifier
Peter Watje (watjep@mindspring.com)

Use this modifier plugin to conform a low-res mesh to an imported ClayTools reference model. This script works best with Editable Mesh objects. It also works well in workflows were a low-res cage is produced, turbosmoothed to introduce more samples and then conformed to the reference model. Here are some recommended options to use when applying the modifier:
Conform Projection = Normal
Projection Direction = Both
Standoff = 0
Collapse % = 100
