Basic Problem
• How to map rectangular images to non-rectangular objects
• Usually, there’s built-in:
• Cube
• Cylinder
• Sphere
• Flat
• What about our character? How do we map that?
The UV Texture editor(Window -> UV Texture Editor)
• Select the dog, then open the editor
The Nose
• Select faces, then Create UVs->Planar Mapping->□ (from Z-axis)
• In UV Editor, RMB and select UV, then select the entire nose
The ARMs
• Start by selecting the faces from *both* hands
• Select the faces on the arms using SHIFT+>
• Follow instructions closely – lots of options!
Paint yer doggie
• Under the “Rendering” set of menus (Texturing->3D Paint Tool->□)
• Make sure the Attribute to Paint is set to Color
• Assign/Edit Textures:
Directly paint on the Geometry
• Turn on File Textures->Extend Seam Color
