06 Detailing Ambient Occlusion
Using Photoshop, I combine the ZBrush PolyPaint and rendered Cavity maps as well as the
desaturated Photo Color map to add more details to the rendered AO map. I also create
Alpha channels with copies of the AO, adjusted lighter or darker to provide masks for
additional detail. I will use the Photoshop Unsharp mask and High Pass filter to add more
variations of Alpha channels to help emphasise detail areas F.

F I use Alpha maps as a mask to quickly add in
highlights and shading to the Ambient
Occlusion map
G Using modo’s 3D Paint I add colour details
such as war paint, fine detail decoration and
scars/battle damage etc
H Skin and leather are low in contrast, while
metal is lighter and has a very high contrast
I Black areas mask material effects, while white
areas reveal them

07 Adding colour
The Ambient Occlusion is used with the Alpha map
variations to add to flat base colours for the Diffuse map.
Each flat colour is a new layer: tan for skin, dark grey for
metal, brown for wood, and so on. Working dark to light, I
load alpha selections to add shaded detail using separate
layers for each pass, then import the flattened map into
modo for further detail work G.
08 Creating specular
I use a copy of the un-flattened Diffuse map as the basis for
the Specular map, with some shaded parts around the eyes,
mouth, hands and underarms inverted to increase spec in
those areas. The overall shading is adjusted for each
material type; flesh is closer to 50% in Hue with low
contrast, metal is lighter with high contrast, while wood and
cloth are darker with high contrast H.

09 Making material masks
To apply different materials such as skin, metal, leather,
wood and bone in modo, I quickly build black-and-white
masks in Photoshop. Each mask will block out one type of
material. I then import each into modo for edge clean-up
and detailing I.
