10.Emissive Materials

自发光材质

Whilst Area Lights are not supported by Precomputed Realtime GI, similar soft lighting effects are still possible using ‘Emissive Materials.’ Like Area Lights, emissive materials emit light across their surface area. They contribute to bounced light in your scene and associated properties such as color and intensity can be changed during gameplay.
然而，区域光并不支持预计算实时GI,类似柔光效果可以使用“自发光材质”。类似区域光效果，自发光材质是从其自表面区域发射光照。他们会在场景中碰撞光照，相关属性也可以在运行时修改，比如颜色和强度。
