Is inline ray tracing (ray query) supported? (Read Only)
Inline ray tracing is an alternative form of ray tracing available in compute shaders and rasterization stages through the RayQuery HLSL object. In DirectX 12 (DX12), this property corresponds to DirectX Raytracing (DXR) Tier 1.1 support.
The RayQuery object is defined in HLSL when you use the DirectX 12 and DirectX Shader Compiler (DXC). Other shader compilers that different platforms use either don’t define the RayQuery object or its name is different. Because of this, the recommended approach is to include the UnityRayQuery.cginc header and use the UnityRayQuery object instead of RayQuery.
