A first look at Unreal Engine 5

Re: A first look at Unreal Engine 5
#622Hundreds of billions of triangles? How much main memory has the PlayStation 5?
i believe the latest rumors suggest 16GB unified GDDR6, but the relevant tech here might be sophisticated caching technology that also leverages a fast PCIe 4.0 SSD
PCIe 4.0 is in the order of Gigabytes per second. Hundreds of billions of triangles would demand hundreds of Gigabytes. There is no way they can calculate this stuff in real time (and tbf, they never claimed that they did).
So presumably, the engine now does that kind of stuff at load-time. The bottleneck is then the place on the SSD and the scene change pace. This fits quite nicely with the repetitive statures, but it leaves a question mark for that final flight.

#623Can someone help me articulate my issue with this? Looking at a lot objects, they seem unnaturally detailed. Like the bugs, or the statue at around 6 minutes. Something about it makes me really uncomfortable feeling physically. Is this like a weird infinite depth of field kind of thing?
There's no distance blur and the entire shot is "in focus". These shots would be impossible to take with a camera. In addition, if you game a bunch, you'd expect LOD to drop with distance, but here it doesn't.
You can take a shot with small aperture and have it all in focus.
The problem here is probably some sharpening filter.

Ah. of course. The system tracked camera and rendered what the camera saw and little around it accurately. Rest was rendered just for lightning.
The guy who developed the tracked camera invented the Roomba (maybe with others? not sure). Pretty cool dude.
I believe I have met him (Burton Conner alum)
Re: A first look at Unreal Engine 5
#625Let me throw in an anecdote that may amuse some: I was working for a now defunct large game company when Epic and Tim Sweeny came in to demo Unreal Engine 3 very early before the PS3 and XBox360 were launched. This was about 2004. Their demo blew away executives in particular. They showed multicolored lights casting multicolored shadows on a single high detail character. One of the lights was behind a stained glass w…

That's actually a different things. Light Propagation Volumes (LPV) is real-time global illumination first used in Cryengine 3 in 2009. http://advances.realtimerendering.com/s2009/Light_Propagatio...
SVOGI (Sparse Voxel Octree Global Illumination) which is first demoed by Unreal 4, yet it never shipped due performances problems. Meanwhile Cryengine manage to get it working with minimal performances penalty (only 10%) and have shipped games with it (Kingdom Come: Deliverance) https://www.youtube.com/watch?v=PEfqtOYjolE

It is not open source in any sense. You can see it so that part is shared but if you try to use it you fall under a very different licease. If you try to modify and sell you can't. Modify and use you must pay. Use you must pay. Bait open source might be a better term.
In the sense of you can see the source, it is open source. Not everyone will agree with your definition of open source.
at some point in the nineties open source initiative emerged as the bastion of what's open source and what not and put strict guideline to the usage of the term, which for whatever reason people around the tech community elected to follow even if OSI doesn't own the open source trademark.
guess it helps the discussion and to defend agains marketing-speak appropriation to have a single uniform definition. but it's confusing as heck if someone is unknowing or resisting the OSI coup to position themselves as the open source regent.

Lots of people arguing schematics. Everyone knows exactly what the guy meant.
I don't see why continuing to argue it makes any sense here. All this type of behavior does is drive people away from further discussions on sites like this, reddit, etc.

#629It's impressive, but personally the Far Cry 5 engine is more so. Why? Because it focuses on the Achilles heels of game engines: humans and forests.

I'm not sure where people get the idea that they can assert something as a counterpoint on no basis. "That's just your opinion," is not a rational basis to disagree, especially when your counterpoint requires the implied basis (semantic) to be equally relevant to the original argument's basis (law). "Open source" isn't based on the semantic that the source code is public, its definition comes exclusively from a set o…
The rationale is people can have different opinion, preference, thinking. People do not always agree with a single definition. No entity has sole authority of a meaning open source.
