Work-in-Progress: VXGI Multi-bounce!
Note that the image below is not from UE4, it’s from our VXGI sample application.
From one of the VXGI developers:
“These images are rendered with the latest version of VXGI, which supports multiple indirect bounces (right column) and with single bounce for comparison (left column). One spot light, no ambient, no light maps, no SSAO.
While multibounce support was primarily added to improve diffuse and specular lighting, it plays really well with refractions too. While we already have support for multibounce in UE, there are no such refractive materials there yet…so it’s not quite ready for release yet.”
