Now go to "Set Foreground
Color". This tool is located here:
 (Click
to Open in New Window)
Click on this to open up
the color pallette (aka Color Picker). You may drag the selection
tool down to the lower most left hand corner, or you may type
in 000000. Here is what this should look like:
Now when we use the Paint
Bucket Tool it will use this black color!
Step
3:
With the Paint Bucket Tool
selected, click on Layer 1 which for example purposes we will
now refer to as "Glow Map Layer". This will fill your
glow map layer with the selected color. Your glow map layer
will now look like this:
Step 4:
Now go to the Layer's tab.
Click on Glow Map Layer. At the top of the Layer Tab are sliders
to set layer transparency. Slide this over to about 50%
Here's an example showing
what your texture and slider will look like:
Step
5:
Now select the Eraser Tool
Now go to
your Brush Options at the bottom of the photoshop upper tool
bar. Select a round brush that is equal to the size of the pupils
(or smaller if you wish to only glow map a section of the pupils)
I recommend a soft edged brush. The size of the brush may be
adjusted here using the slider under the brush, or a number
may be entered in.
For this example, select
the soft edged 27 pixel round brush shown. Enter in 25 in the
number box as shown.
Select the opacity to your
desired amount of glow. Remember, the more color on the glow
map the more it will glow. I usually use 50% for a slight glow.
You may change the opacity of the brush in the brush tool bar
as shown below:

Step
6:
Now center the brush over
the pupils and left click. Your texture will now look like this
Not much of a change quite
yet.
Step
7:
Now adjust your Glow Map
Layer to 100% opacity. Here is your glow mapped eye texture:
At this point
you may apply it to the mesh. However, for further example purposes
we are also going to glow map the lips. The eye only glow map
PSD has been included in the zip file.
Here's an example render
with the glow map applied with lights on and lights off:
Once again,
I only used slight glow mapping on her eyes to not overwealm
the face. You can adjust the intensity by increasing the opacity
of the eraser brush.
You may also duplicate
your background layer if you wish your eyes to glow a different
color than the eye texture. Simply duplicate the background
layer and color it as you please. Just make sure it's underneath
the glow map layer. For ease, this should be done after completing
all the above steps.
You may also choose to
glow map only sections of the eyes, such as small spots of twinkle.
To do this, use a smaller eraser brush.
Glow
Mapping the Lips
Glow mapping lips can be
difficult, as too much glow map results in clown like lips that
stand out from the face too much.
Follow all the above steps.
Once you've succesfully glow mapped your eyes, make the Glow
Map Layer 50% opacity once again.
Select the
eraser tool once more. This time select a very small number
for brush opacity, I perfer 10%.
 (Click
to Open in New Window)
Now, run the eraser tool over the Glow Map layer like we did
with the pupils. Run the tool over the top of the bottom lip
and at the crests of the top lip. Here's an example marked in
red of where to use the eraser tool.
Here's an
example of what your texture will look like after using the
eraser tool on the partially transparent Glow Map layer:
Now, adust
the Glow Map Layer to 100. You won't see much difference on
the lip section of the texture:
Now, save your texture
and apply it to the mesh. Here's a render of how the lips look:
Once again, by increasing
the opacity of the brush tool or increasing the area of the
lips glow mapped, you can set varing stages and intensity of
glow.
