New Havok physics system: due by Summer 2019 Real-ray tracing will become available in an experimental build of the HDRP on GitHub on 4 April 2018, with a full public preview due in ‘fall 2019’, presumably as part of Unity 2019.3Įpic Games is already supporting RTX-based ray tracing in Unreal Engine 4.22, currently in public beta.

Unity’s blog post describes the rendering work as being done at “interactive frame rates” using Nvidia’s GeForce RTX 2080 Ti gaming GPUs.ĭuring the corresponding section of the keynote, which starts at 02:02:40, you can see a 13-million-poly car interior scene being manipulated in real time on a single-GPU laptop. The firm’s demo of the technology (embedded above), which was created with Nvidia and BMW, intercuts footage of a real car with a CG car rendered at 4K resolution in Unity using the HDRP. The system is built on top of the new High Definition Render Pipline (HDRP), introduced in Unity 2018.2, using C# scripts and shaders. Unity’s implementation of real-time ray tracing is based around RTX, Nvidia’s hardware implementation for the DirectX Raytracing API, available in its new Quadro RTX, Titan RTX and GeForce RTX GPUs.

The functionality, which is built on Nvidia’s RTX technology, will become available as a public preview later this year, as will a new physics system based on Havok’s middleware. Unity Technologies has announced new real-time ray tracing capabilities for its Unity game engine during its keynote at the GDC 2019 conference. Scroll down for news of the preview release of Havok physics.
