Resolved Runtime GI

I think official is planning to implement inhouse GI solution long time ago but ends up return back Enligten. I would like to know does official still working on inhouse GI solution that does not rely on Raytracing? I would like to see Runtime GI solution happening at both URP and HDRP.

 

I would like to add more context that I expect GI solution that work at runtime that doesn't need to do any pre-baking process. Will official implement it?

 

That's excellent news! Do you have any ETA on this? Enlighten is supposed to be deprecated (again) in 2023 as per this official post, so does that mean we'll have something working before the end of next year?
Can you share more informations on how it is supposed to work? (what techniques are in use? Is it supposed to work alongside/replace APV?...)

The whole situation around realtime GI in Unity was an absolute mess (Enlighten being deprecated without any replacement available, said replacement solution being eventually sent into oblivion without further comments, then Enlighten added back without any of its missing updates...), and I can't help but wonder why no communication was made around this.
I understand performant realtime GI is a massive undertaking, but I don't think some level of transparency on the work and progress done would actually hurt anyone.

Anyways, can't wait to see what you've got in store for that!

 

Do you plan to allow the pre-computation step to be baked/updated/modified on demand in runtime (like after procedurally generating the scene or modifying it) or is it planned only for 'offline' editor baking?

Thanks.

 

Will this 'fully dynamic lighting and geometry with no precomputation' mode be an extension of the same system as the baked version? I mean do you plan to have one base system for both modes? Or maybe the plan is to have two separate systems with more differences than just baked/dynamic modes?

What about 'dynamic lighting and geometry with no precomputation' mode. Will it be based on light probes/some kind of DDGI but with a dynamic geometry update?

Thanks.

 

Hi, does it mean that this in-house solution will not rely on light maps?

 

Do you mean new apv state blending or it will be another system

 

Interesting, thanks for your answer! I'm really curious about the baking part though, what informations are getting baked?

 

Hi, will these information ("New Enlighten", "Full Real Time GI") appear on the GI roadmap?

 

@Matjio If i am understanding correctly, u guys are working on both a precomputed GI and another a complete dynamic one? Is this correct? Is the complete dynamic one similar to lumen, does it handle reflections too??

 

Is it possible that in the future the new GI will use raytracing api optionally to achieve better quality/faster updates (like using more probes and updating them faster/more often). Or maybe the plan is to not use raytracing for this system at all, even optionally.

 

Could you at least please confirm that they will be released before Enlighten deprecation, or that Enlighten's deprecation date will be pushed back if they're not ready? Realtime GI is a must for some projects, and while SSGI is neat it definitely can't replace non-screen space GI.

 

Or at least in preview stage when removing Enlighten.

 

I'm excited about this, most things I worked on didn't require dynamic geometry GI, just static all around, so that alone will help many projects. As long as we don't have to worry about UVs, and baking times aren't crazy

 

Hi, we make simulators with physics, and most of the projects is Ship related, the ship is moving on the sea..
Is it possible to make the probe system relative to the moving ship? (not only the world) The ship is like an scene in itself and can be marked as static for lightning..
