I am not sure if this has been answered already, but as a newbe to Blender V2.73a, I have listed the steps I have taken so far and what I need to achieve.
Created a plane, scaled to 25 blender units in X and Y plane
Subdivided this into 65,536 faces
Sculpted a terrain from the plane using sculpt mode
UV Un-Wrapped and Texture painted the entire terrain
What I need to achieve now is it break this single mesh object into 5 equal pieces across the X and Y plane so that each piece (now 5 x 5) can be exported as a separate collada file complete with its texture map for import into Secondlife. I have trawled youtube and wiki and the various forums but with no joy...I am also rubbish at phython, so I am on bended knee in the hope that some kind person can provide an answer..
Many thanks in advance...Kushiel
