Core Purpose of UE Rendering
UE’s rendering system is used to output high-quality still images and animations from real-time scenes. By combining lighting, materials, cameras, and post-processing, it enables near cinematic-level visual results.
1. Rendering Methods & Global Illumination
- Use Lumen for real-time global illumination and reflections
- Use Ray Tracing for higher accuracy lighting and reflections
- Balance visual quality and performance based on project needs
2. Lighting System
- Work with Directional, Point, Spot, and Rect Lights
- Control light intensity, color, and shadow quality
- Use volumetric lighting and fog to enhance depth and atmosphere
3. Materials & Textures
- Follow a PBR material workflow (Base Color, Roughness, Metallic)
- Optimize texture resolution and use material instances
- Apply normal maps and transparency for surface detail
4. Post Processing
- Manage exposure and disable Auto Exposure when needed
- Adjust color grading, contrast, and saturation
- Use effects such as Bloom, Vignette, and Depth of Field
5. Movie Render Queue (Final Output)
- Render high-quality images and animations using Movie Render Queue
- Configure anti-aliasing, motion blur, and warm-up frames
- Ensure consistency between the viewport and final renders
