merci! alfred wallace,i’m going to try to answer at this question of bacgrounds:modelised or no; well, both: i texture or a plane 3d, or more often a curved plane surface" meshed",often whith a photo , then AFTER i go gently in zadd or sub or m, to deform (a little) the plane, and it is able to take light, and to enhance 3d feeling; of course it’s only for bakgrounds, or very imprecise form…in the picts i join: first,just a photo of the little country road behind a friend’s farm: it was just to show to friends at the moment what happens in 3d: i apply the numeric photo on a plane 3d, then change as you see the form a little, and the light (more); it’s not modelled, it’s a little modelled!
