How to stop streaming lightmaps?

Hey people,

I have this annoying issue where lightmaps get streamed. The floor is using the biggest lightmap ( 2k res - it needs it)

I’ve tried increasing streamingpoolsize , unchecked compress lightmaps, tried changing LightmapStreamingFactor & ShadowmapStreamingFactor to both 0 or 1…in BaseEngine.ini ( they don’t seem to change anything).

If I fly away from the floor ( so it goes to a small screen percentage ) than it loads the full lightmap and stays like that but that doesnt help since the user won’t be able to do that.This seems like a bug to me ? I’ve read the Texture Streaming documentation. Before 4.15 this was never a problem.

Project Settings>Engine>Rendering>Textures>Texture Streaming… Disable it.

Thanks but I would like to disable streaming only for the lightmaps.Streaming all the other textures is still a welcomed feature.

in the world settings you can see this lightmaps and manually disable mipmaps by double click of them

That is, until you build lighting again…
