Landscape heightmap texture streaming?
If "Project Settings" > Engine > Rendering > Texture Streaming is True, when I start the game (Launch on Windows or command line), the scene is rendered, however, at the beginning, landscape height is not accurate, after a while, the height is correct.
If Texture Streaming is False, I experience longer loading time before the scene starts to be rendered, but I don't see the height inaccuracy once the scene is presented.
It could also be that the geometry LOD is not at 0 at the beginning, but how can I eliminate the problem?
The landscape heightmap textures should stream in almost instantly. How long does it take for you?

Looks like the engine does not prioritize streaming in mipmap 0 of HeightmapTexture or not prioritize the nearest component's mesh to be generated first.
"r.TextureStreaming 0" results in similar effect.
I can use the Move Level tool to move the "component on which player is spawned" to another level (Loading.umap, which is small and loaded very fast), and Load the other landscape components as a Streaming Level.
Maybe should utilize World Composition.
