I was working on Inworldz today on my Firefly starship.
Because they don't have arbitrary, no-reason, silly constraints... I managed to link the entire 768 prim, 80 meter long ship into one object.
This means I don't have to use a Multi-Move flight script (and the resultant lag) to move the ship.
It means the ship doesn't move like a can in a tornado with pieces catching up with one another... but as one linked piece, smoothly (or relatively so).
It means I don't have to worry about a ship consisting of 12 different pieces that can fly apart at a sim server whim.
It means Linky Labs can bite my scaley liddle dwagon hiney, wot it means. Their arbitrary limitations have hurt my builds long enough. From now on... I'm not gonna waste my time developing new, complex builds on SL. That is one major, frustrating waste of time and effort. Inworldz just rocks. :D
