Thanks to all the people who replied, I was not expecting so fast and so kind answers....but I'm getting aware of the fact that I forgot to tell you what version of Poser I was using. and the models I had...so...I use Poser ProPack, Posette, Dork, Vic 1, Mike 1, V2 and M2. I can't use Poser 5 for some obvious reasons: I'm on a mac. As for V3, I just can't buy her now...And mainly not yet in my priorities because I'm really starting up on the 3D modeling hobby (I'm not constant at practicing and I have less time to play now...) As for fluorescent lighting (I'm talking about those white tubes that light the offices at no cost), it's because this is the kind of lighting that is used in a metro wagon... Thank you all for your kind and understanding answers... PH
