Achieving Higher Visual Fidelity with Ray Tracing
summary
Step-by-step setup for Unreal Engine 4.25 ray tracing: enable DX12 and ray tracing, turn off the reflection denoiser via console to get crisp rays, set G-Buffer to Use High Precision Normal and enable per-mesh High Precision Tangents to remove swimming normals, fix HDRI Backdrop’s Sky Distance Threshold (from 1 to ~6000) so reflection captures build, balance hybrid tracing with PostProcess.MaxRoughness (default 0.6; ray trace all at 1 costs ~4 ms) and skylight samples, and export using Movie Render Queue (example: 5 spatial, 3 temporal samples).
