Bug :
-Level with TS enabled.
-Load level during gameplay to a level with no TS -> Clouds still visible.
: Or just click new level and the clouds are still visible even tough there is absolutely nothing on the outliner.
: Or disable TS in one level, and it is disabled in another level when opened (as in the boolean is “visible” but no clouds).
4.18.1 / Latest TS build / nvd 1070 gpu.
Edit :
Bug 2 : Reflection captures do not see the sky and capture black instead. Same with skylight.
