Explanation: What can Unreal Engine 5 do?.
The demo of Epic’s new engine has become very spectacular: on the PS5, the details of the animation running without any pre-rendering are also analyzed in text and in an explanatory video with Hungarian subtitles.
It was a heartwarming feeling to watch the Unreal Engine 5 demo released by Epic Games in two ways: on the one hand, there was finally something more tangible about the PlayStation 5, and on the other hand, the visuals and sound were really stunning, especially knowing that nothing in the video rendered or post-patched element, all live, directly a “creature” of the game engine. In an official video released yesterday, two Epic Games experts dissected what was seen, to sum it up now.
Brian Karis, technical director at Epic Games, comments on the news with Jerome Platteaux, the art director responsible for making the demo. This reveals a lot about what has been added to the engine as a novelty and what elements are being refined, for example, compared to the 4.25 version released recently. This is also subtitled in Hungarian, to view it click on the CC button in the lower right corner of the player, if it does not appear automatically.
Unreal Engine 5 comes to light
One of the two innovations is Lumen, which is reforming the entire light treatment. Not only is it able to dynamically handle the illumination of all elements and the transformation of shadows at the same time as the position of the light sources changes, but the refractions and reflections also change immediately, automatically depending on the direction and other properties of the incident lights. The technology also more realistically reproduces the properties of light reflected from metal and other reflective surfaces.
And Nanite is a technology that can import even more detailed, movie-level elements into scenes, even those used in games, by converting them without losing quality without smoldering all the memory in the machine and graphics controller. This is achieved by dynamically transforming 8K resolution elements of up to billions of triangles into far fewer polygons, filtering out those that are not currently visible from the player’s perspective. One of the most shocking moments in the explanatory video is when the image you just see is broken down into triangles – most of the many millions of polygons look like a single pixel, or even image noise, even though each is handled separately by Nanite technology.
The sculptures at the end of the demo each consist of 33 million polygons, and no scams have been used to display them, so even when we see them from a distance, they use a model with a smaller number of polygons, possibly placing bump folders on a flat surface. And yes, this also applies to the scene where hundreds of sculptures can be seen: each featuring its own 33 million small triangles from start to finish.
In addition to the two completely new features, other little things and improvements can be seen in the demo. The behavior of bats flying out of a cave, or beetles that respond dynamically to light, is performed by a system called Niagara, which constantly monitors the environment as well as communicates between elements, so a swarm of bats or beetles move as if they were a creature of really many creatures. we would see a community responding to changes in the environment as a group.
They are also grated on how the characters and elements of the environment adapt to each other, in the case of the protagonist climbing the rock, this can be seen in the more realistic way of placing the foot, bending the limbs and positioning the body. The physics of liquids has also become even more realistic, and the Chaos simulating the behavior of solids introduced in Unreal Engine 4 has also been updated.
Finally, a lot of work has been done on the sound system as well, the echo of real places is even more perfectly reproduced by the new engine, just as it has been made more realistic as each real spatial sound is transferred to virtual space.
We still have to wait
We are very curious about how the new and updated features will be exploited by games based on Unreal Engine 5, which according to official information we will expect from 2021, so the PS5 and Xbox Series X (after all, of course, not only on the Sony console, but on the day of the release of Microsoft’s new machine, and by the way the current generation, as well as PC and mobile platforms) no one should expect such results as usual, the hardware performance will not start well optimized 1-2 years later use by developers.
By the way, we already know that – not very surprisingly – Fortnite will also switch to the new graphics engine (not when it comes out, but later), and the current generation and mobile games will not be left without UE5 support.
