Okay, I did some work, finally found some fish! :) I found them at www.planit3d.com they are 3ds files fully textured and colored :) its' great! I took out the caustics (obvioulsy), I got the idea of the colors from the national geographic pictures of the Bismark and Titanic wreck photos. I tried to light the interior of the Natalus but I guess the windows aren't clear. I also want to get more of a spotlight effect coming from the submarine I think I almost have it, I'm not sure what I'm missing on that matter. I think the picture also needs something more, again, I'm not sure what I'm missing. My sister was a diver but she has been putting in heanous hours at her job, so feedback from her is rather difficult at present. Again, thanks for all the help Herne
