Hi,
Not sure if it might be useful to anyone else, but here's a variation of the TextureRenderer which can be used for offscreen rendering (i.e. use your rendered scene outside of the main jME context). I use it to display a radar (HUD style) in another SWT view. See for yourself: http://sanctuaireone.free.fr/screens/radar4.jpg
