Hello,


Quickly make a small nut.

But i can't see that the thread is helical.
How do you see it?

If you look at the bottom of the hole, you'll see where the thread tapers off.
If you want to accentuate that, if you're using a difference {}, then you could
use a slightly different pigment color, or a normal.

You could even just change the lighting and cast a harsher shadow.

I see it clearly in the hole, and a little bit on the front. Maybe 
rotate it 60 degrees so the end points of the helix are in frame.

Almost see it. Slightly rotating that nut could probably make it more 
visible. Maybe just a 15° to 30° clockwise rotation would be enough.
Then, shifting the light's location could also help.
Finally, the thread is often more shiny than the exterior of the nut. 
That may also help.

hi,

indeed, by working on the light, it's more obvious
thank you for your advice.



after all, it's just a nut...
