I’m using GPU lightmass in Unreal 4.27.2, with “Enable Virtual Texture lightmaps” set to true.
I’ve manage to reduce the “popping” of lightmap texture when moving the camera, fallowing this topic:
However, I have some issues with lightmaps in raytracing reflections.
I have some mirror in my scene and they really look awful until I turn the camera on the other side to load the lightmap textures.
Any idea how to force the loading of Virtual Textures (lightmap) in the reflections (or in the entier level)?
I would honestly just turn the Virtual Texture off, but the editor crash when a build GPU lightmass without it.
