Unity currently supports advanced ray tracing in the High Definition Render Pipeline (HDRP). We are exploring the possibility of extending similar capabilities to the Universal Render Pipeline (URP). This exploration includes evaluating the integration of ray tracing effects using DirectX Raytracing (DXR), Vulkan, and Metal APIs for a range of devices, including high-end mobile phones and laptops.
Potential Ray Tracing Effects for Consideration:
- Ray-Traced Shadows (Ambient Occlusion, Soft Shadows, etc.)
- Ray-Traced Reflections
- Global Illumination
Technical Considerations:
Integrating ray tracing into URP involves navigating complex technical challenges. Our primary goal is to ensure that any enhancements do not compromise the flexibility and customization options that URP users rely on. We are carefully evaluating the impact of ray tracing on the core architecture of URP, ensuring that any potential implementation aligns with the pipeline's design principles and user needs.
Performance Impact:
The integration of ray tracing effects could significantly enhance visual quality but may also impact performance, particularly on untethered or mobile devices. We aim to investigate the balance between visual fidelity and performance efficiency.
User Feedback:
We are interested in your perspective! Please vote on this card to express your interest in ray tracing effects for URP and to help us understand your priorities. Your feedback is valuable in guiding our exploration and potential prioritization.
