I have just run through the video's made by Realspawn - they have helped me understand the art of coding which is sadly lacking in the manual. The manual just states a few lines of code - Realspawn has shown how to join 'em up!
I have(off and on)been using 3dg for almost ten years - and at last someone has explained 'cameras' clearly !!
More of the same, please, Realspawn.
