2. What is UV Unwrapping?
• UV Unwrapping is the process of converting a
3D model’s surface into a 2D map.
• This map allows textures to be painted and
placed accurately onto 3D objects.
3. Role of UV Coordinates
• U (horizontal) and V (vertical) define the 2D
space for textures.
• They work like latitude and longitude for
model surfaces.
4. Steps in UV Unwrapping
• • Clean and prepare the mesh
• • Mark seams to control flattening
• • Unwrap the model into UV islands
• • Pack and scale the islands efficiently
5. Why It Matters in Games
• • Accurate texturing without distortion
• • Optimized texture space usage
• • Reduces memory and improves
performance
6. Unwrapping Methods
• • Planar Projection – best for flat areas
• • Cylindrical – for tubes or limbs
• • Spherical – for round shapes
• • Smart UV Project – automatic unwrapping
7. Effective UV Layout Tips
• • Hide seams in less visible areas
• • Keep consistent texel size
• • Avoid overlaps unless intentional
• • Use checker patterns to validate UVs
8. Software for UV Unwrapping
• • Blender – intuitive UV tools
• • Autodesk Maya – professional 3D package
• • Substance Painter – for painting directly on
UVs
9. Pitfalls and Fixes
• • Stretching: from poor island layout
• • Seams: visible if placed poorly
• • Overlaps: cause texture errors
10. Advanced Mapping Concepts
• • UDIM tiles for high-res details
• • Ptex for UV-less mapping
• • Multi-tile for texture streaming
11. Real Example: Game Asset UVs
• • Game model: sci-fi helmet
• • UVs: cylindrical + planar methods
• • Result: seamless, optimized texture
12. Recap
• • UV mapping links textures to 3D forms
• • Careful unwrapping improves visual quality
• • Use correct tools and techniques
