SSGI seems rather noisy.
It's good for static lighting, not dynamic.
If it solves dynamic lighting denoising, it is competitor for unicorn GI.
It's interesting that enlighten is deprecated and soon removed before they introduce a replacement Realtime solution.
Except for the artifacts inherent to screen space techniques. A screen-space pre-trace followed by real ray tracing is the way to go as demonstrated in Metro Exodus.
It's not that interesting at all. They have to license Enlighten.
The blog post said it's because Geometrics is shutting it down as a product. Still no deeper "conspiracy", it's just their hand was forced a little early.
They're discontinuing the version Unity is using, I'm pretty sure. They still talk about the updates they're giving to UE4 on their blog.
I personally do not care about Enlighten being deprecated, I do not use it any more, but the way Unity discontinued it without much warning and screwed everyone that had built their games around it is giving me "dropping Beast without warning" PTSD like flashbacks.
And for clarity, it was Unity that dropped it. Their hand was not forced, if they really wanted to, they could keep having Enlighten for the foreseeable future.
Now that we settled this, let's hope the new stuff comes quickly and is decent.
That is understandable then.
Unity already has DXR in SRP for Nvidia. I would imagine enlighten with raytracing would cost more.
DDGI was working since early 2019.2 so it's in testing phase. They aim to expand for AMD.
I think that is better to have everything within SRP than 3rd party solution which will require additional maintenance on top of everything.
Unity should create hardware agnostic raytracing and DDGI.
RTX Lightprobes FTW
I've dealt with enough stuff like this comment to notice exactly what's not being said. He mentions continued support. He does not mention cost.
Sure, maybe, I don’t know. I also feel like Unity wasn’t feeling like paying anything at all really after the S***show Enlighten was in 5.x. And I can’t blame them too much for that.
The problem is that they announced the deprecation without a replacement ready and they demonstrably have known for a while. Ever since Silicon Studio bought Enlighten I asked what it meant for the Unity integration but was met with silence. Even though they knew.
They could have a solution ready, like now, or told us much earlier, or they could take one for the team and pay silicon studio whatever they wanted for a few more years, I mean Unity recently had a price hike for no benefit to us users at all and we’re paying. It’s business.
Maybe Silicon Studio was being unreasonable, but seeing how Unity ended up handling things, I am not really willing to give them the benefit of the doubt and assume they handled this in a way that even remotely prioritized their users’ well being.
Which is “fine”, because corporations, especially big ones, like money and are assholes, and Unity is a corporation, just so we’re all on the same page.
It's not that simple. There was a study some time ago and if I remember only 27%-30% of Unity developers use enlighten.
How many of those are paid subscribers?
Unity is changing. SRP is still experimental.
Integrating it now with SRP and knowing it'll change with 3.10 SDK in summer, plain and simple is not a good strategy.
Enlighten is in 2019.4.LTS.
RTXGI is very close.
If 30% isn't enough usage for Unity to bother to maintain a feature, I... I really don't know what to say any more.
I wonder how popular Collaborate is.
Or Umbra. That's licensed too.
And I doubt 30% uses HDRP.
People use Enlighten mostly for the lightmapping. The progressive lightmapper takes care of that. For the rest there's always the asset store.
Does anybody know of released games that actually use the real-time GI feature of Enlighten?
Possibly tons more but it’s hard to know which game actually uses Enlighten and which not.
HDRP only recently stopped being an experimental feature and is being developed in-house.
Can't be too many since the complaints about Enlighten's removal are few.
Taking a moment out to remember our fallen comrades, enlighten and LM'ing in general. Gonna miss ya.
Also update on the poll results shows 130% in favour of yes, 68% yes and 67% yes.
*Poll kinda reminds me of a Russian Polling Station.
So? Maintaining a team is probably as expensive. Again if 30% is how much a feature needs to used for Unity to maintain it, we are doomed. That’s not a game engine then, it will quickly morph into like a very fancy Facebook client.
Maintaining a team is generally something that happens as part of running a business, which is a sharp contrast to Enlighten, which I wager was only being used because it was in the engine due to the license.
People generally don't like Enlighten. I know a good amount of people who wish Unity was still using Beast.
And I am one of them. But I bet less than 30% used that too, since the GI features were Pro only, huh... Maybe that’s why they removed it without a second thought.
Actually it's because Beast was outright completely discontinued in 2017, but the writing was on the wall before 5.x even came out
I know. The writing was on the wall for years, and they replaced it with the most broken implementation on Enlighten ever, which I guess is more than good enough for a feature that was used by less than 30%
I am trying to argue that the 30% argument is horrible, since game engines should be tools that give you the freedom to do all kinds of things and as such should have a ton of features that only small percentages use. It's a tool and a feature that I use once, but really helps me that one time, is a useful feature. There's a place for the "it wasn't very popular" argument in software, but it's not in game engines or OSes.
That is the argument I am trying to make but you are arguing about everything around that.
I mean, really, if HDRP was final and was used by 20% of people it would obviously be a useful feature to have.
30% is actually a lot and definitely not a number where depreciation should be considered.
Yeah, 20 or 30% use of a feature would be considered a huge success in many areas.
Nvidias website gives a general availability date of 2020 for RTXGI.
Yes, https://developer.nvidia.com/rtxgi-technology. It says in the bottom page 2020. Around Unity 2020.1/.2?
And what percent of that uses the real-time features of Enlighten vs just the lightmapping?
I just saw the picture on the first page again. The contrast is so low in that picture, must be worse than enlightens precomputed GI? I wonder how many f-stops enlighten Realtime GI has, the human eye have around 10 to 14. I'm guessing Realtime GI is below a cell phone camera even
