Landscape Material rendering issue only in packaged game


when testing in editor the snow on the mountains is fully visible, but in the packaged version it is not. when looking at the mountain at the side of the field of vieuw sometimes the snow does show.

the map is 8k by 8k and the distance to the mountains is several KM when closer the snow does turn up again, causing me to think I might have just missed a settin when it comes to the landscape or landscape material.

when changing th Field of View to < 80 the snow apears again in the packaged version
