3D modelling for computer games
This subtopic focuses on the application of 3D modelling techniques specifically for computer games, covering the creation of low-polygon models optimized for real-time rendering. Learners will develop practical skills in using industry-standard software to model, texture, and export assets, while also learning to evaluate their work against professional standards and game design requirements.
Assessment criteria
Learning Objectives
What you need to know and understand
- Explain the principles of low-polygon modelling for real-time rendering in games
- Apply polygon reduction techniques to create efficient game-ready models
- Create UV maps and apply textures to 3D models for visual fidelity
- Export 3D models in appropriate formats for integration into game engines
- Evaluate a 3D model against technical and aesthetic criteria for games
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct use of edge loops and topology for deformation
- Award credit for showing efficient polygon count appropriate for target platform
- Award credit for producing UV maps with minimal distortion and efficient use of texture space
- Award credit for applying textures that align correctly with the model's UV layout
- Award credit for exporting the model in a format compatible with common game engines (e.g., FBX, OBJ)
Assessment Guidance
Guidance for achieving higher grades
- 💡Practice modelling with a focus on maintaining clean topology and efficient polygon use
- 💡Always check your UV maps by applying a checker texture to identify distortion
- 💡Export your model and test it in a game engine like Unity or Unreal to ensure compatibility
- 💡Document your workflow and decisions to support your evaluation and justify your choices
Common Mistakes
Common errors to avoid in your coursework
- Creating models with excessively high polygon counts unsuitable for real-time rendering
- Neglecting to optimize topology, leading to poor deformation or rendering artifacts
- Improper UV mapping resulting in stretched or misaligned textures
- Using textures that are too large or not optimized for game performance
- Failing to test the model in a game engine environment before final submission
