Here's a 3ds Max 9 script to create sculptie textures.
SculptGenMax is a lightweight script that allows users to create sculptie prims in 3ds Max and export them to Second Life.


The forum thread is [http://forums.secondlife.com/showthread.php?t=185426 here].
=== Current Version ===


NOTE: I'm not saying that this is a better way to do it. If you are using a method that bakes textures and it's working for you, there is no reason to try this.
SculptGenMax will no longer be released as a standalone product.  


This algorithm generates the texture from the vertices. In contrast to most baking methods which generate the texture from the faces. It's not clear to me yet if one method is better than the other.
It is now a part of [http://liferain.com/downloads/primcomposer/ Prim Composer].


Anyway, instructions are in the script. It will *not* work on an arbitrary mesh. To simplify things, I used a particular cylinder or sphere mesh as my starting point. Instructions for creating the mesh are in the script.
Prim Composer is complete offline building environment for Second Life and OpenSim. Build in 3ds Max; Deploy to either Second Life or OpenSim. Both prims and sculpties supported.


Feel free to modify it for your own personal use and post bugs and fixes in the forum thread or the comments section below.

--
-- This is a MAXScript written for 3ds Max 9.  It might work for earlier versions of 3ds Max,
-- but this has not been tested.  It does not work for Max5.
--
-- The script generates a Second Life sculptie texture from the selected object.
--
-- Revision History
-- ====================
-- 0.2 First released version
-- 0.2.1 Added proportional
-- 0.2.2 Fixed rotation issues
--
-- 0.3      Shifted bitmap by 1 pixel in X and Y.  changed defaults "NO SMOOTH" 128x128
--          no longer have to move the top and bottom vertices when you create the object.
--
-- 0.3.1 added x:, y:, and z: display boxes, so that you can know what dimensions to use
-- on your prim if you have the proportional feature turned off
--
-- 0.4 a) sculptmap now matches the 3dsMax UV map.
-- You should now be able to bake textures using the UV map and they
-- should line up with the sculptie in SL. NOTE: because I now use the UV map, if
-- your sculptie looks inside out, then your UV map is probably wrong.
-- b) only one vertex is used in the top and bottom row of the cylinder.  The vertices
-- used are the top and bottom vertices on the seam of the UV map,
-- i.e., the vertices at the top left and bottom left of the UV map.
-- c) sculptmap now has one more row of data.  The cylinder should be 32x32.
-- sculptmap conforms to http://forums.secondlife.com/showpost.php?p=1522861
-- d) smooth feature removed.  wasn't helpful.
-- e) 32x32 option removed.  64x64 is the lowest resolution sculptmap supported.
-- I might change this later, but it needs work to support 32x32 properly.
-- f) now supports a NURBS cylinder. See description below.
-- 0.4.1 a) fixed bug with UV map. Now handles UV maps correctly that have more vertices than are
-- in the mesh.
-- b) Poly sphere 32x32 supported.
-- c) NURBS Sphere 32x32 supported.
-- d) added drop down to allow you to change the uv map channel that is used.
-- *** CREATING THE POLY/MESH OBJECT ***
-- The script assumes a specific topology for the object.  You **CANNOT** use the script on
-- an arbitrary mesh.
--
-- Create the following object as a starting point:
-- 1) create a cylinder with 32 height segments and 32 side segments
-- 2) Apply an Edit Mesh modifier
-- 3) delete the vertex in the top and the vertex in the bottom
--
-- Now, you can move the vertices any way that you like.
--
-- When you're done, make sure that the object is selected and generate the texture.
--
-- NOTE: as of Version 0.4.1, you can also use a sphere. You need a 32x32 poly or mesh sphere.
-- The easiest way to create this is to follow the directions for the NURBS sphere
--      and then convert to mesh or poly.
-- *** CREATING THE NURBS OBJECT ***
-- As of Version 0.4, you can also use a NURBS cylinder as your starting object.
-- As of Version 0.4.1, you can use a NURBS Sphere.
--
-- 1) Create a cylinder or sphere
-- 2) Convert to NURBS
-- 3) If cylinder (skip for sphere), expand the "NURBS Surface" modifier and select "Surface" under it.
-- Select and delete the top and bottom of the cylinder.
-- 3) Go back to "NURBS Surface".
-- In the NURBS "Surface Approximation" Rollout, select Tessellation Method "Regular"
-- and set U Steps and V Steps to 32.
-- Now, you can NURB away.  Hint: Select NURBS Surface>Surface CV to see control vertices
-- When you're done, make sure that the object is selected and generate the texture.
-- *** SCRIPT INSTALLATION ***
-- MAXScript>Run Script...
-- in the dialog, select the script and press Open.
-- Customize>Customize User Interface...
-- click on the Toolbars tab. Select Category "SecondLife".  Drag SculptGenMax to one of the
-- toolbars.
--
-- *** RUNNING THE SCRIPT ***
-- Install script
-- Create object, modify it as desired, and select it.
-- Press SculptGenMax in the toolbar where you installed it.
-- A dialog will pop up.  Select desired bitmap resolution.  Then on the dialog's menu bar,
-- File>Generate Sculpt Texture
-- this will generate the texture in the dialog.
-- File>Save as..
-- to save the texture to a file.
--
-- *** UNINSTALLING THE SCRIPT ***
-- Right click on the SculptGenMax button in the toolbar and select "Delete Button".
-- Find the file "SecondLife-SculptGenMax.mcr" and delete it.
-- Restart 3ds Max
--
