The current project requires Unreal Engine 5.3 running on a high-end Windows PC. Over time, we should be able to migrate to next-gen Mac, VR, AR, and smartphone platforms as they improve (and UE improves). For now, here are some settings that improve the realism and performance of TimeWalk:

Movie Render Queue Settings

  1. Enable Streaming (under World Settings/World Partition Setup). This will load only the landscape tiles that are in view at any time.
  2. Set LOD 0 Screen Size to 4.0 (default is 0.5) under Outliner/Environment/Landscape1609/Details. Screenshot below.
  3. Build HLODs to prepare for streaming (Build/Build HLOD). Do this after changing LOD 0 screen size to 4 (see above).
  4. After "Building HLODs", you can set LOD 0 Screen Size back to 0.5
  5. Alter the "Loading Range" (under World Settings/Runtime Settings). Default is 76800 (0.78km). Try larger numbers.
  6. Enable hardware ray tracing (Edit → Project Settings → Engine → Rendering) if your graphics card supports it
