Hi, I made a copy of BP_Sky_Sphere from Engine content and tweaked it for a cloudy night. It looks good both in viewport and when i launch the scene, but when i export a movie from Matinee the reflections is like the standard BP_Sky_Sphere? Any ideas? Thanks!
I updated from 4.7.2 to 4.7.5 and now its working. Never mind 
If you run into this again just update the sky light(if you have one in the level) and reflection captures in your level every time you make a change in your sky sphere or lighting…
Thanks Jacky! I’ll remember to do that
