Thanks Hugo!

I was very tired, so before I went to sleep I decided to leave it with a
high setting of focal blur :)

OK. I'll try to thicken it a bit more, and maybe I'll use torii instead of
cylinders to round them. However, I wanted to give them a "sharp" look, but
maybe you're right.

Actually that's kinda accidental! :) The projection of the bump map causes
the sides of the bolts to look like that... However, I didn't dislike it
that much, because it makes them look like "scratched" from the fabrication
process. But I'll fiddle with this, let's see what happens.

4) The bolt texture has a nearly

The problem is that when I emphasized the normal map in the top of the
bolts, then the "lateral scratches" looked too strong... But I'll try to fix
it.

No :) Today in the morning I began to use a bit reflection and it really
helps a lot.

6) It's green.

I tried to give it the same illumination effect that Jaime's raytracing has,
but I think I fell short of many things, because it doesn't look that good

Thanks Hugo! I'll take into account your suggestions!

Fernando.

PS. BTW, this are the previous "brazilian bolts" posts that I found:

Please be properly seated and firmly hold on to something before opening
Jaime's raytracing!
