We can assume a high likelihood that Epic is going to introduce Tessellation and Displacement back into UE5, there are now increasing multiple user threads discussing and requesting this, and it actually winds up becoming a great marketing opportunity. No isolated discussion in one thread alone encapsulates that there is a vast user base that would enjoy the introduction of these tools into UE5, and that marketplace visits would inevitably increase per such introduction. Every marketplace developer should support this.
Looking at 5.1 build, there is no Nanite functionality for skeletal meshes still. Nanite’s abilities undoubtedly hold great promise for the future, but optimized usage of past assets are now being shown by the user-base to rely heavily on Tessellation and Displacement, as was available in UE4.
