Hi Islam,
Probably this area of the forum is not appropriate for the discussions on rendering in Max. I, like most of your works, would like to model in ArchiCAD and render in Max, the problem I have are mainly in texturing and lighting.
But as this is not the area for that discussion may you can provide me with your e-mail address so as to discuss on specific problems. Mine you can find at my profile. I would appreciate if you could assist me.
