Unreal Engine 5.4 Released

Hi @Amanda.Schade @Matthew.Ivey ,

nanite

Please, make Ray Traced shadows usable (at least, even if not fully compatible) with Nanite. Even if using Nanite Mode 1, shadows will show spot areas/triangles over distance (from 5 or 10 meters in advance). Very similar will also happen when not using Nanite, but when using LODs, in some of the LODs distances. In addition, foliage WPO is not compatible with RT shadows if Nanite is enabled.

And please, improve Virtual ShadowMaps. In many cases, they are less performant than RT shadows and, in addition, they are super noisy in movement (for example, in a dark interior, with a light behind a slow spinning fan -if faster it’s much worse-).

Conclusion: how to use high quality shadows? We can’t use RT shadows unless you don’t use Nanite and force all LODs to Zero… And we can’t use Virtual Shadowmaps as they are not that “high quality” and are super noisy unless your project is totally static and quite light (not dark).

Thanks!
