I'm better to use only one program if possible. I have enough work with Bitrun, pCreator, Blender, 3DWings and Kimera only to edit a model. The benefit is that it is possible to make complex movement scripts in a much faster time. With Ochu I have to start the game, have to make a plan how the route does look that a certain NPC is walking, have to write down the cords and then I have to take them over to MR into the script. If everything is good I like the result, if not (which is most likely) I want to change certain positions which let me do the whole thing again (if I'm lucky I don't need to reopen FF7 because I have foreseen that this will happen). If I can edit the (movement)position visibly I spare simply time and have more time for the creative process. And because we all do moding the game in our spare time (which is currently for me near zero), a time win and less complex method will bring us more advanced mods.
