New Features Of Unreal Engine Release
Unreal Engine 5.3 brings further improvement to the core UE5 toolset. This release delivers improvements in a wide variety of areas, including Rendering, Worldbuilding, Procedural Content Generation (PCG), Animation and Modeling tools, Virtual Production, Simulation, and more.
Rendering And Lumen
Lumen Reflections support more than one bounce when hardware ray tracing (HWRT) is enabled with Hit Lighting, and the Max Reflection Bounces setting in the post process volume is set to 2 or greater. This can prevent black areas in reflections when there is enough performance budget to allow it. Full list of changes in Lumen
Cine Cam Rig Rail
Filmmakers can now emulate the workflow and results of traditional camera movement along tracks or on dollies, thanks to a new Cine Cam Rig Rail Actor.
Skeletal Editor (Experimental)
Skeletal Editor offers faster iterations by means of the addition of bones to your assets, the deformation of static meshes, and converting them to skeletal meshes, all in one place without the need for importing skeleton data.
