 Features:
 
 - Unidirectional pathtracing with NEE and skyportals
-- Principled BSDF, filmic tonemapping
+- Principled BSDF, filmic tonemapping, physical sky
 - Automatic texture compression
 - CPU backend accelerated using SSE/AVX/NEON extensions
 - GPU backends (Vulkan, DirectX 12) with optional HW raytracing
