After many previews, Epic Games has finally released a new version of its Unreal Engine 4 to all interested developers. The final build 4.23 added a preliminary version of the Chaos physics and destruction system, made many improvements and optimizations to the implementation of real-time ray tracing, and added a beta version of virtual texturing technology.
In more detail, Chaos is a new high-performance physics and destruction system for the Unreal Engine. She first during GDC 2019 and then Epic Games published . With Chaos, users can experience real-time cinematic-quality visuals in scenes with massive destruction and an unprecedented level of artist control over content creation.
Ray tracing hybrid rendering methods have received a lot of performance and stability optimizations. Some new features have also been added. In particular, version 4.23 improves the quality of noise reduction algorithms and improves the quality of global illumination using ray tracing.
The operation of the multiple reflections mode has also been improved (in particular, reflections inside reflections after a certain specified rendering level will display not black dots, but a color created by the rasterization method). Technology Capabilities another example of the 4.22 engine using the Troll demo created by Goodbye Kansas and Deep Forest Films:
Finally, Unreal Engine 4.23 added preliminary support for virtual texturing, that is, the ability to apply a mipmap not to the entire object, but to its parts. The technology will allow developers to create and use large textures while using video memory more carefully and predictably on large objects.
Among the innovations, we can mention the Unreal Insights tools, which allow you to more effectively analyze the operation of the engine and the game being developed. Chaos was also tied into Niagara's sprite particle system for more spectacular smoke and dust destruction. A lot of optimizations and improvements have been made.
