Tip
For best results when creating any 2D artwork on a computer, I highly re-
commend purchasing a graphics tablet. A mouse is good for work that re-
quires more precision, but for drawing it's not a very fluid tool. Graphics
tablets are also pressure sensitive, meaning you can vary the thickness of
the line you are drawing by applying more or less pressure. The two main
suppliers of graphics tablets are Wacom (

)
and Nisis
(

Image Preparation
To begin, we will load in our UV snapshot and prepare the image so we can use it effi-
ciently. We need to invert the UV snapshot so we have black lines on a white background.
We can then use this as an overlay, guiding us as we paint underneath it.
1.
Open up Photoshop and load in the file called KilaHeadUV.tga.
2.
Go to Image > Adjust > Invert (Ctrl+I/Cmd+I).
3.
Now you need to duplicate this image and then create a separate layer with it, so
first go to Select > All (Ctrl+A/Cmd+A) to select the entire image.
4.
To remove the selected image from the background layer and place it in a layer of
its own, go to Edit > Cut (Ctrl+X/Cmd+X), followed by Edit > Paste (Ctrl+V/Cm-
d+V). This creates a new layer for you in the Layers window (
Figure 9.2
) called
Layer 1.
