These Blender scripts provide Second Life® sculptie map support to Blender. They use the addMultiresLevel feature that was introduced in Blender 2.46
copy the .py files to your Blender scripts directory as listed below.
Linux: ~/.blender/scripts
Mac: /Applications/blender/blender.app/Contents/MacOS/.blender/scripts/
Windows XP: c:\Program Files\Blender Foundation\Blender\.blender\scripts
Windows Vista: C:\Users\USERNAME\AppData\Roaming\Blender Foundation\Blender\.blender\scripts
Note: The exact directory may change depending on install version, but should be something like the ones listed. Mac users may need to enable viewing all files to find the correct folder.
If you can't find your scripts directory, then create a new text in Blender and paste the following code into it:
import Blender
print Blender.Get('scriptsdir')
If you press alt-p ( File - Run Python Script ) then the correct directory to install the scripts will be printed on the console.
Run Blender and in the "File - Import" menu you should see a new option for 'Second Life Sculptie'
If the option is missing, select the scripts window and use "Scripts - Update Menus" to refresh the menus.
