The All Incredible Unreal Engine 4 Got Ray Tracing Support
Epic has announced the latest preview version of Unreal Engine 4 this week and it now comes with both low-level and high-level support for ray tracing. Enabling developers who use the game’s powerful engine to create can now add support for the NVIDIA reflection technology Providing a boost for NVIDIA’s RTX cards, Yes, it is a huge deal for gaming.
“Peek into the future of real-time computer graphics with “Reflections,” the first demonstration of real-time raytracing in Unreal Engine 4 using Microsoft’s new DXR framework and NVIDIA RTX technology for Volta GPUs. The Reflections demo illustrates the next-gen experimental lighting and rendering techniques in Unreal Engine, developed in collaboration with NVIDIA and ILMxLAB.”
Unreal Engine developers’ new ray tracing options, from the UE 4.22 preview notes:
“Real-Time Ray Tracing and Path Tracing (Early Access). Added ray tracing low-level support: Implemented a low-level layer on top of UE DirectX 12 that provides support for DXR and allows creating and using ray tracing shaders (ray generation shaders, hit shaders, etc) to add ray tracing effects.”
Added high-level ray tracing features:
– Rect area lights
– Soft shadows
– Reflected shadows
– Ambient occlusion
– RTGI (real-time global illumination)
– Geometry types: Triangle meshes, Static, Skeletal (Morph targets & Skin cache), Niagara particles support
– Texture LOD
– Shadows, Reflections, AO
– Path Tracert
– Unbiased, full GI path tracer for making ground truth reference renders inside UE4.
