Development Rendering

Hi everyone,

I performed all the steps to enable LPV GI. I made

  • edit the “ConsoleVariables.ini” file, I add r.LightPropagationVolume=1 at the bottom, right below the [Startup] category
  • *Directional Light and Skky Light moveable
  • E*nable Dynamic Indirect Lighting on the Directional Light.
  • Project Settings > Rendering Enable Generate Mesh Distance Fields and Enable Generate Landscape Real time Gİ
    *- *World Settings = “Force No Precomputed Lighting” which is located under the Lightmass category, check the checkbox to disable the use of Lightmass.
  • I add post process settings with unbound and i changed value of LPV intensty

But nothing happens. I checked visualizins LPV but again nothing happens.
Where am i doing wrong ? Can you help me this issue, please.

There is this guy which has the Unreal Lighting Academy post somewhere in the forum, but I saved this link here and you can browse for more: Unreal 4 Lighting Academy - Session 2.2 - YouTube

I just use the LPV in 4.20 for my testing, and everything looks good. I definitely found no problem in your steps, since you are taking steps in the doc. Light Propagation Volumes | Unreal Engine Documentation.

btw, do you restarted the engine after editing the consoleVariable.ini file and distance field related settings?( probably yes

Thank you. I have done it.

LPV doesn’t work with Subsurface Profile, right now 4.26
