Xenic101, here is an attempt to faking ambience - I followed the suggestions by Thuleke: 1 dome with hdri True ambience 1 light cast shadows 256 rpp As you can see, TA avoid that the shadows are too much dark - and there is no grain. Of course, at that high rpp the render took about 22 hrs on an Athlon 2500 XP with 512 DDR 400... :P
