If your mesh contains CPV color, PlyEdit has a number of tools for touching up or completely replacing that color information.

Color Tools

Fig 1. 3D Paint
Fig 1. 3D Paint
Clear 
The color of all faces is set to white.
Mask 
The color of all unmarked faces is set to black.
Recolor 
Overlays a representation of the surface shading into the color itself.
Gamma 
Globally lighten (values less than 1) or darken (values greater than 1) the color information.
Smooth 
Smooths the color by the level indicated.

3D Paint

There is no painting within PlyEdit itself; what the 3D Paint tool does is provides an interface between PlyEdit and 2D paint programs. The only requirement is that the paint application can read and write TIFF formatted image files.

In this description GIMP, a free multi-platform application (see gimp.org), is used as the external 2D paintbox. Commercial products, such as Photoshop, would work just as well.

The painting process is quite simple:

Step 1] 
Select a view of the polymesh that you would like to paint.
In this situation an Ortho projection may be better than Persp as parts of the polymesh further from the camera will be given the same pixel coverage as closer parts.
Also consider hiding parts of the polymesh that you don't want to paint. Say you have a whole creature, but only wanted to paint the head, hide the rest of the body. This will speed up the color export and import process.
Step 2] 
Fig 3. Step 2: Extract Color
Fig 3. Step 2: Extract Color
Click the Extract button. This writes the color and surface shading into two separate files; by default, out.p.tif and out.s.tif.
To change the filename prefix edit the Name field. To change the save directory, click on the right arrow after the Name field.
The left side of Fig 3 shows the extracted color, a blank canvas because Clear was used before painting, and the right side is the surface shading.
