maybe something can be done to smooth this out. What makes this very noticeable is how close to the player this happens and that it happens all over, not at just some radius.
Surely there is some technological solution for a smoother transition between lod models instead of this pop-in stuff? Maybe more inbetween versions? I don't know what the engine supports.
It should be pretty much seamless.
