Hi, Hugo!

Actually, I didn't do much to the black texture, but I did reposition the
lights to properly show off the contours.

Well, yes, you're right. It would be more physically accurate with blurred
reflection, but as there are no actual light objects (i.e. lamps, bulbs) to
reflect, you would not have seen any highlights on it at all, so I opted for
specular. If/when I integrate this into a real scene, I will redo the
texture.

I really don't feel that it's so slow... Unless you make it reflect against
other blurred textures, but especially when you use it on transparent
objects, *then* it's slow - to the point of being impractical.

<snips trick> I'll keep it in mind, thanks.

Actually, I just tweaked the image_map of the granite (desaturated, played
with levels), and used that as a bump_map. I wasn't really going for blurred
reflection, just trying to give the surface a more 3D feel.

I want a digital camera... waaa....

Thanks. Although this should be my last render with this model. I would like
to move on and do others. It's satisfactory for me as-is. It's not
hyper-realistic, but realistic enough for me. :)
