Why? Objects in the world are not perfect. When creating three
dimensional models, the inclusion of dirt is an items baptism.
While some scenes call for more dirt than others, texturing objects
to reflect use is a skill worthy of the attention of any aspiring
artist.

PROCEDURALS Procedurals are mathematical functions which coat
patterns over the surface of a material. Multiple procedurals can
be used on the same object to create a grungy look.

Slide 5
TEXTURE MAPPING Assigning a file to the color node of a objects
material. One approach to texture mapping a large surface of
uncertain dimensions is to use a seamless tile. One can also import
an image to be used a single time as a decal or painting.

UV MAPPING Another approach involves organizing and exporting
the UVs of an object to allow a custom-fitted skin for components
of a model. Window UV Texture Editor Polygons UV Snapshot

PAINT EFFECTS One can also use 2D paint effects to paint grunge
directly onto the model in Maya. Render menu set Paint Effects Make

OTHER METHODS Superimposing a translucent, colorized version of
an ambient occlusion map onto the items texture map. Using light
and a transfer map to assess areas with a higher concentrations of
dirt.

COMBINATION & EXPERIMENTATION There is no wrong answer. A
combination of methods often renders a pleasing look.
