Hi,
Thankyou to everyone who provided comments on this image. I'm adjusting
the model right now to take into account the improvements suggested by
everybody. I particularly like the idea of having a plaque on the
machine. This is delaying the render of the machine in it's full
sparking glory even further :)
However, on the point of the textures, I think I'm getting rather more
credit than I deserve - I'm afraid to say that the wood textures are not
procedural - they just use image maps :(
I gave up on procedural textures after I couldn't obtain satifactory
results. If anyone is still interested, both a description of how I
obtained the maps and the texture with the image/bump maps is appended
below.
The wood texture was obtained by searching auction pages for images of
antique furniture, so obtaining a detail of a small teak table. I
copied a section of the wood texure and adjusted it to tile neatly in
Photoshop. I then "dyed" copies of it to get appropriate colors for both
the machine and the table. Copying this, desaturating and adjusting the
curves gave the grain bump map.
