Brutal Engine ships with several production-ready integrators, each optimized for specific lighting scenarios.

Path Tracing (Unidirectional)

The standard workhorse for general rendering. Efficiently handles direct lighting and simple indirect bounces. Best for outdoor scenes and studio setups.

BDPT (Bidirectional Path Tracing)

A more advanced algorithm that traces light from both the camera and the light sources. It excels in difficult lighting conditions, such as:

• Interiors dominated by indirect light (caustics).
• Hidden light sources.
• Glass and liquid rendering.

Wavefront

A highly parallel execution mode designed for maximum throughput on modern CPUs, minimizing lane divergence.
