..swapped the wine/glass with drinking beer from a can...

Yes well, seems we have run out of wine anyway. Remind me to lock that cupboard next time teenagers stay home alone.

Funny what happens during week-end shopping. The stupid mistake in above example dawned on me over a display of avocados: The Y-axis values are calculated from the wrong side of the model, so the light-sources are placed outside the lamp-shade, hence the wrong reflection. Also, the lampshade needs a different material on the inside.

Fixing the co-ordinates, and setting the inside of the lampshade to a material transparency to an .mtl value of d 0.5, the result suddenly became much closer to what I wanted.

Yes, I know, certainly nowhere near perfect, but the lamp model is now getting closer to usable. The remaining issues should be fixable.

Thanks a lot to cec for steering me in the right direction. Time for some Saturday cooking and a ... well, can ... of something. Updated/corrected SF page .
