I think things depend on what the contest is judging. If the is judging how good an image "you" can make in "particular progam", then you should use "only" that program. No other applications, third pary clothes, textures, props, etc., "you" do everything. That way,(except for talent and experience, the playing field is even). Note; Poser 4 and Poser 5 are two different programs, because you can do things in Poser 5 that you cannot do in poser 4, including better rendering, and that does not make a level playing field for people who donot have both. For the most part, contests would be determine by money. If you can afford "Professional" programs, then that give you an unfair advantage, and people who have several "professionl" programs would have an advantage over people who have none or one professional programs. Every body needs the same Professional program(s), and number of programs to make a level playing field. If you can afford the fantastic Mats, Props, figures, lighting that's available, that gives you unfair advantage over people who cannot afford to puchase them. Should people who have training/talent/professioal experience in 2D art be put in another catagory of the contest, they would have an unfair advantage in post work etc). Should people who are Professioal 3D artists also be put in yet another catagory, (to make a level playing field)? If you are an amatuer but knows enough to make your own mats, and props in Poser should you be put in another catagory, because of the advantage you have over non skilled people? I'm sure, with a little thought, I could come up with more "unfair" advantages. What do you think? :OP
