Using
a noise texture this time I made loads of spots, once I was happy i've converted
to file again and put with other layers in photoshop.
Here's
my crazy spot texture opened in photoshop and put with my other layers.
Next
i've used a brownian texture to make the very fine wrinkles that you might see
on the forehead or around the neck. Converted to file texture again.
Now
for some pot marks.
The
pot mark texture opened in photoshop; we are only actually going to use it in
a few places like the nose and around his cheeks, we will erase the rest.
Now
I have started to blend the textures together, starting with the first texture,
and doing some test renders at the same time to see how its looking. erasing areas
of the textures and blending it with my 50% gray layer right at the bottom using
soft light, or multiply or overlay.
Now
looking at the spot texture, we of course only want some random spots and bumps
here and there so I will be erasing most of them.
Now
we need to be making lots of test renders while we work on the bump map, there's
only really a few areas of this spot map that I want to keep. I like the big lump
that's above his left eye, i'll probably try and keep that in.
I've
started fading out areas of the spot map. You see i've tried to keep the lump
over his eyebrow.
To
blend different bump layers together try using soft light or overlay with opacity
just experiment and see what works best.
My
spot map with areas faded, poor old guy he's got loads of spots, but your hardly
see them in the final texture.
Now
playing around with the fine wrinkle layer its only really useful in a few places.
Now
the pot mark layer i've used levels adjustment to make the spots darker. then
blended them with the other layers.
Now
on a new layer i've started painting in some wrinkles using a small brush and
low opacity.
Now
here's a little tip that can help painting maps a little easier. I render out
a simple baked texture, the lighting I used was Dr Emmanuel Campin's GI Joe lighting
dome (Link). if your going to try baking
a texture with a lot of lights, it can take a while so do it at night or something
when your not using your pc.
