PEP Texture Applicator
Find it: Click its button on the Looks palette: 
Use to:
-
Fine-tune textures to get rid of seams on PEP objects.
-
Break off instanced polygons to remap texture.
-
Specify exactly how the texture gets mapped onto a face of an object.

For step-by-step information on using the PEP Texture Applicator, see Fine-tuning a Texture.
The Menu Bar:
-
File
-
Interactive Change--turn off if rendering in the preview
window is slow. Default is on.
-
Close--remember to click Apply to save your
changes before closing the PEP Texture Applicator.
-
Edit
-
Undo and redo of local operations.
-
Break Instancing--breaks sharing of texture coordinates
between polygons. This lets you change the texture mapping on selected
polygons only.
-
Merge Selection--makes the selected polygons share
texture coordinates where they coincide.
-
View
-
View Selection--zooms in to mapping of selected polygons
-
View All--zooms in or out to mapping of all polygons in
object
-
Auto View Selection--interactively zooms as you select
polygons
-
Mappings--use to get best texture mappings for object shape.
By default, the Texture Editor maps the
texture to the most prevalent surface of a model and smears the texture
across the rest of the model. Using Mappings, you can change
this mapping to reduce or eliminate smearing. For example, to get the
best texture mapping for a chess piece, choose Cylinder:Best. You
can also select mappings specific to X, Y, and Z combinations.
Mapping applies to the current polygon selection--if nothing is
selected, it applies to the entire object. This enables you to map
different functions to different parts of an object.
