Here is my second mcpov image. I'm happy with everything but the wood texture.
It looks good enough away from the hub, but at the hub it comes off as
"plasticky" to me.

Here is the texture callout:

  //base wood texture
  texture{ T_Wood7 rotate 90*x scale 3 finish{ ambient 0 diffuse .3 } }
  //colored "overlay" to reduce the contrast on the wood grain
  texture{
    pigment{ color rgbf <238/255,226/255,168/255,.65> }
    }
  //white stripes on tips
  texture{
    pigment{
      gradient y
      color_map{
        [ 0.0 color rgb 1 ]
        [ 0.1 color rgb 1 ]
        [ 0.1 color Clear ]
        [ 0.12 color Clear ]
        [ 0.12 color rgb 1 ]
        [ 0.14 color rgb 1 ]
        [ 0.14 color Clear ]
        [ 1.0 color Clear ]
        }
      scale 140 translate 10*y
      }
    finish{ diffuse .9 }
   }
  //clearcoat
  texture{
    pigment{ color Clear }
    finish{ phong .7 phong_size 100 reflection {.5 fresnel} }
    }

the mesh also adds: interior{ ior 1.8 }

The lighting is with an HDR probe, and the reflection provides the "glossiness".

I tried actually actually putting a clear envelope around it with ior to
simulate clearcoat, but it didn't turn out very well.

Anybody have any ideas to give the wood some more depth?

It actually doesn't look that bad.

If you do want to improve the appearance, add some subtleties to the grain.
Look in the standard wood texture include for starters for some layering
techniques.


Also try with warping at multiple scales (i.e. scale a pattern up/down apply
warp, then scale back).  This can help as well.

Very nice image, and nice textures on everything--wood included.

If the wood seems too much like plastic to you, though, then you might turn down
the reflection a bit and perhaps add a very subtle normal map with the same
pattern that you use for the pigment.  I don't know if that would be at all
realistic, since I would think any piece of wood that was to be used as a
propeller would be about as plasticy-smooth as you could hope for.

If it were me, though, I think I'd leave it as-is.  It looks great to me.

I have to say that's an amazing metal texture you have there, complete 
with micro-ridges and such.  Is it an image map or is mcpov providing 
some finer texturing or lighting features?

mcpov really helps out with the anti-aliasing, but here is the texture for the
brushed metal. It was better than I hoped it would turn out.


   texture {
    pigment{ colour rgb 1 }
    finish{ ambient 0 diffuse .8 specular .8 roughness .1 brilliance 2 metallic
reflection {.35} }
    normal{ waves 0.35 frequency 2 scale 0.004 turbulence .2 }
   }

I concur. To me, that wood just looks like it has been heavily varnished.

Add a nice texture for your tabletop, and you're good. :-)
