Hi all,

I`ve just gone through both Tapes this weekend, while the techniques are
excellent for a beginner, I noticed that I already knew these techniques,
and I use slightly different ways to get a more impressive surface.

For those of you who followed Ron`s tutorial, when your creating the diffuse
and specular map for the metaformed hull, and wing tips, and your using
PhotoShop, try the following.

    Diffuse Map
    In the same way Ron used the selection tool to brighten and darken
    areas with Bright/Contrast control, use Add Noise of 4 to 12 to give
    the surface a varying amount of diffused dirt. Vary this on different
    panels.

    Specular Map
    Same again, but this time, use a high noise factor 48-64 on dark and
    blackened areas, and a value of 32'ish on grey areas, and no noise on
    light areas. This gives the surface a great look!

   Bump Map
    Obvious right?  I wondered why Ron missed this, I`ve been using a
    slight bump map to enhance panels for years now,  When you first
    draw your light anti-aliased lines to divide up the surface, save
    these, add contrast to brighten them up, make the background black
    and add the bump map at around -20 to -30% to recess the bump effect.

These techniques make the surface look much better than it did when I first
completed the ship, following Rons Techniques. I`ll upload an Image to
Tomahawk later to demonstrate the look.

rgds,

Steve Davis.
