Nice tutorial it will be ! I agree that ambient light must be avoided. I can' wait to see your tut. One problem with the light is there is no universal solution ; indoor scenes are more easy to light than outdoors. And among indoor scenes, single objects are really easy to light; perfection can be obtained in such cases (Sascha your glass picture was probably near perfection). But for an interior with lot of objects, the problem becomes harder. I made a lot of tests during the past weeks, and tried several possibilities, most of them for single objects : - 1,2,...spotlights around a group of objects - lot of pointlights (up to > 100 but this one was in preview mode) In most of the cases I used soften settings for the light but in that case we are obliged to render in high quality so, even with a simple scene, rendering time is >10h There are several way to place the lights (spheric dome , plane, line,...). It depends of the scene itself, of course. Generally Sure, 2 pictures, one with lot of ambient, one with your special (and good) settings, should be a very convincing test. Hope to continue such interesting exchanges ;=) Yves
