Export sculpties as LSL

Simply select "Second Life LSL" from the "File - Export" menu and choose a directory to export to.

This will save the selected sculptie's map and texture plus a short LSL script to recreate the prim inworld.

Import to Second Life^®

In Second Life^®, upload the .tga files from the directory. Create a new prim and edit the contents. Add the .tga files to the contents. Create a "New Script" in the contents and edit it.

In a text editor open the .LSL file, select all and copy.

Go back to Second Life^® and select all the script then paste the script you copied from the text editor over it. Save the script and it will run and turn the prim into the sculptie you exported from Blender.
