Oh dang, I knew Lumberyard was going open source I did not know it was because they were done. I’ll remove it than the next time I update the post.
I don’t know much about Dlux either myself. I have headed a couple of conversations about it a while ago. They look like they could be quite the gem if some game devs are able to work things out.
For now it seems people are mostly doing photo things with them from what I could tell. I don't have a VR headset so It's not something I knew much about.
