The skylight settings seem to be the same. I’m not sure where to see if I’m missing reflection captures in the 5.4 version but I could’t find it in the 5.1 ether. maybe I’m looking from wrong place, I’m quite new to unreal engine. It seems my water shader is the same in both projects so I haven’t figured out what’s making the difference in the 5.4 version. What exactly do you mean by the reflection captures?
