Unity has officially unveiled the impressive “Time Ghost” tech demo, showcasing the powerful capabilities of the upcoming Unity 6 engine, set to release on October 17. This demo continues Unity’s tradition of pushing visual boundaries, following up on their earlier demos such as “The Blacksmith” and “Book of the Dead.”
The visuals in Time Ghost are remarkable, thanks to Unity’s updated High Definition Render Pipeline (HDRP) and advancements in lighting, like Adaptive Probe Volumes (APVs) and Smoke Lighting. These features, along with the improved GPU Resident Drawer, ensure smooth, high-performance graphics, even in complex scenarios.
One of the demo’s unique features is its use of machine learning to simulate cloth deformation in real time. By training a model with 2,000 frames of vertex animation, Unity has reduced data size from 2.5 GB to just 47 MB, achieving precise cloth physics that only takes 0.8 milliseconds per frame to process.
The demo also highlights Unity 6’s enhanced hair simulation system, which was first introduced in the Enemies demo but is now more robust with seamless LOD generation and realistic wind effects.
While the visuals are nearly photorealistic, some character animations, particularly during running sequences, still appear slightly stiff, a minor issue developers are likely working to refine.
Unity 6 promises to be a major step forward for developers, offering tools like the VFX Graph and Shader Graph for detailed control over visual effects. The engine also includes an improved VFX collision system, enhancing the stability and realism of in-game interactions.
