Oh, that is beautiful, Laurent! It looks like a very old painting. I keep looking at it. :) X-TC, when using the OBJ import, some Poser textures (particularly body/skin stuff) usually needs to be flipped. In the Y scale of the material use -1 and that will do the trick, most usually. As Bloodsong mentioned, the green line might be due to the bump being set too strongly. Check the Bump tab of the material and set the Gain to something like .2 or even .02 -- bumps come on strong in Vue and the smaller numbers usually work out best. :)
