Thanks! Didn’t get the skype invite though, just in case the username is pachesantiago (hotmail.com)
Yeah, saw it a while back. From the look on the screens is voxel cone tracing, with the same trick as VXGI to get “unlimited” bounces by reusing the prev frame voxel grid to accumulate bounces on the filtering stage. It’s not really correct, but works well enough in most cases.
Still, looks polished, didn’t knew the guy had continued working on it. Performance seems a bit problematic though, 45 - 60 fps at 1080p on a GTX Titan is not that good, but it’s still an early alpha.
