Hi Dave What's Imagine Constant Upgrage Program (IFW2.1.4) already has that IFW doesn't have: 1)volumetrics fog with shade inside 2)volumetric lights 3)zmesh: take three comletely independant objects, a neck, a torso and a arm, design a part of the neck as fillet.neck, part of the torso as fillet.neck and another part (the lateral part of the torso) as fillet.arm, design a part of the arm (the upper part) as fillet.arm, all the corresponding fillet parts will then be filleted. then can be grouped hierarchically and animated and also, the textures applied to the objects mesh accordingly, they can even be boned I think, but I never tried it. 4) some cosmetic improvement in the graphical interface What 3.0 is supposed to have: 1) a single interface for the the stage and detail editor 2) a full 3d spline, that I am not so sure, nobody talk much about that 3) atmospherics, yes maybe in addition to volumetrics that's all I can see or remember right now, we havn't had any updated informations from Impulse from a while. Some people were upset about that, but what do you gonna do? All I know is that 3.0 is still a project at work. Richard
