I agree with @SavvyIndoorsman… just to comment that if you’d prefer to adjust the default physics volume settings… there are a couple of places where you might be able to intervene:
– In Project settings > Engine > Physics > Default Fluid Friction
– In BP with Get Physics Volume and dragging out Set Fluid Friction (need character Reference)… If you are only using the default physics volume… I’d just do once on BeginPlay.
Btw… as far as I remember, the first option might not work, but it’s worth trying…
