An attempt at Raytracing

• I used the following sources
  • Unreal Engine Ray Tracing Tutorial
  • Create a Mirror Material in UE4
  • On Line Documentation
• First of all
  • Neither my machine, nor the machine in the lab seem to have the horsepower to do this.
  • You probably want the latest graphics card. (GEFORCE RTX *)
    • And neither appear to have this.
    • Oh drat, I wanted something short anyhow.
  • And possibly more cores than I have
  • 
• I started with the third person shooter
• I deleted almost everything from the scene.
• I added a plane to the scene.
• I wanted a reflective texture for the plane, so I created one
  • Using the second tutorial
  • You create a new texture
  • 
  • Open this in the editor
  • Set the base color to white.
  • Set metalic to 1
  • Set Specular to 1
  • Set roughness to 0
  • 
• Next change some settings.
  • Under Platforms
  • Go to Windows
    • Change the Default RHI to be DirectX 12
      • In the tutorial he has you start a new version of the engine using DX12
      • But in the documentation they say to do this.
      • I bet this is a change to the engine since the video was produced.
      • But I could be wrong, since I can't get anything to look really good.
  • Under Engine
  • Go to Rendering
    • Find Ray Tracing
    • Turn this on.
    • It will also want to turn on Support Compute Skincache
    • This will want to restart the engine
    • And Rebuild ALL OF THE LIGHTS
