Now
here's a small bit about the textures, mostly the
bump map. This character is meant to be really old
and have lots and lots of wrinkles.
In
the final version he's not as old looking as I would
of liked. I did model him with the intention of
taking him in to zbrush and adding a lot of details
like lumps and bumps and wrinkles then making a
displacement map from it for the lower res version.
But after testing I just don't have the memory or
using the right renderer to achieve this.
Anyway
for starters on the bump map, the textures for just
his face were 4096 by 4096, which was reduced to
3072 by 3072 for the final texture. I first painted
the above map in Deeppaint 3d. I just quickly painted
lots of lines that I wanted my wrinkles to run,
so its easier for me to paint when I open this texture
in photoshop.
Now
here's that texture opened in photoshop I've put
a 50% gray layer on top of it and turned the opacity
down a bit so I can see the texture I painted in
deeppaint , I will be painting on the gray layer
using colour dodge and colour burn
using
colour dodge I've started painting lots of wrinkles
following the lines of the layer underneath
using
colour burn as well now
sorry
but I've moved along quite a bit now this is now
the almost finished bump map some different layers
have been added. Some spot layers also some layers
with very fine wrinkles
here's
some bump map tests, some displacement was used
in these pics. For the final version I just used
normal bump mapping
