Source Engine 2 represents a major leap in level design capabilities. The Hammer Editor, Valve's proprietary tool, allows designers to create competitive maps for CS2, Dota 2, and Deadlock.
Getting Started with Hammer
The Hammer Editor comes bundled with Valve's games. To access it, navigate to your Steam library and enable the tools for CS2 or Dota 2.
Greyboxing Your Level
Start with simple brushes to block out your level geometry. Focus on sightlines, choke points, and rotation paths before adding any detail.
Lighting and Atmosphere
Source 2 uses a physically-based rendering system. Use environment lights for outdoor scenes and point lights for interior spaces.
Optimization Tips
- Use areaportals to control visibility
- Implement hint brushes to guide the vis compiler
- Keep draw calls under control with texture atlasing
Conclusion
Source 2's Hammer Editor is a powerful tool for competitive level design. Master the fundamentals before moving to advanced techniques.
