Welcome to “Global Illumination” or “GI is really, really hard.”
I wouldn’t be surprised if it would be a while until this comes in. And for that matter Light Propagation Volumes with the right extensions will already handle the most important parts (Shadowing from the environement) of this. So I’d just go to the timeline and vote for that.
These are already done and in latest, but haven’t all made it into a release yet.
>Shadowing from the environment on movable objects and translucency
>Static version
>Sky light reflections don’t work properly with TLM_Surface lit translucency
>Sky lights don’t work on mobile platforms
This is in progress, but it is a very difficult problem and might not work out (the shadowing part of it specifically)
> Movable version
We haven’t updated the docs yet. I’ll pass along the request to get the rest on the roadmap.
