[FYI] tiago.costa Original CL Desc ----------------------------------------------------------------- Improvements to tracking of proxies requiring invalidation when raytracing geometry is streamed/built/made resident. Context: - The existing CachedRayTracingStateProxiesMap mapped [UStaticMesh -> Array of Proxies that need to be invalidated], however there was no way to map [FRayTracingGeometry -> Array of Proxies that need to be invalidated] since FRayTracingGeometry doesn't have a pointer to which UStaticMesh owns it. On top of that, not every FRayTracingGeometry is associated with a UStaticMesh. - An alternative approach could be having a map [FRayTracingGeometry -> Array of Proxies that need to be invalidated] however that would require significantly more memory - O(#proxies x #LODs) instead of O(#proxies). Change: - Modified CachedRayTracingStateProxiesMap to use a more generic RayTracing::GeometryGroupHandle (int32) as key. - Store RayTracing::GeometryGroupHandle in FRayTracingGeometry. #rb aleksander.netzel [CL 31016413 by tiantian xie in ue5-main branch]
