@thisnorthernboy Often it's just learning to post-process the original asset (e.g. make LODs, bake tiny gribblies into textures etc) but it always starts from the original model and works from there so it's just an extension to your process, not an invalidation of it. And UE now even actively promotes plugging original high poly meshes directly in and letting the engine sort it out. But it's a lot of experimentation & iteration for everyone since the tech is constantly changing anyhow
