What is the difference between Eevee and Cycles?
Eevee: speed and real-time
Eevee is designed for speed, using rasterization techniques similar to game engines. It renders almost instantly, making it great for viewport previews and quick animations. However, it approximates global illumination and reflections, so it may not handle complex light interactions as accurately as Cycles.
Eevee supports many features like screen space reflections, soft shadows, and bloom, but they require enabling and tweaking. It's ideal for stylized renders, motion graphics, and situations where speed matters more than photorealism.
- Real-time rendering, very fast
- Uses rasterization, approximations
- Good for animations and stylized looks
- Requires enabling effects like SSR and soft shadows
- Less accurate for caustics and complex lighting
Cycles: realism and accuracy
Cycles is a path tracer, meaning it simulates the actual behavior of light rays. This results in highly realistic lighting, shadows, reflections, and refractions. It's the go-to for photorealistic product renders and architectural visualization.
The trade-off is speed: Cycles can be slow, especially with complex scenes or limited hardware. However, it supports GPU rendering and denoising, which help. You can also use lower sample counts with denoising for faster results.
- Path tracing for physically accurate light
- Slower but more realistic
- Supports GPU rendering and denoising
- Best for photorealistic stills
- Handles caustics and complex materials well
Common mistakes
- Assuming Eevee is always faster; in some scenes with many effects, it can slow down.
- Using Cycles for simple previews when Eevee would suffice, wasting time.
- Forgetting to enable necessary settings in Eevee, like Screen Space Reflections, leading to flat-looking materials.
