Hi Tommy, I’d just like to say a massive thank you for making this possible. I make heavy use of emissive lighting in my projects, and it was really disappointing that the stock Ray Tracing implementation doesn’t support it. I have a couple of quick questions if that’s ok?
Does this support GI bounce for emissive lighting? I think I’m only seeing direct lighting from emissives.
I get no Ray Tracing at all on spline meshes (not even path tracing), which I’m assuming is something Epic need to add to the RT engine itself?
Thanks again, and I’ve included I scene I’m working on which is lit 100% by RT emissives
