Is it possible to reduce the water level on the Z-axis in Water Body Lake. Otherwise, my project will be completely flooded.

See from what I have seen you use the Z axis to adjust it downwards to create your depth, however the problem when you make it too deep is the Z+ axis creates a collision box ABOVE the water. -\_-

If you are referring to the official Water plugin for UE, you have to open the material for the water (ie. “Water\_Material\_Lake”) and enable the **UseFixedZ** parameter. This will allow you to manually adjust the Z axis of the water actor in your level.

But I did not see **UseFixedZ** parameter in UE4.27, how can I adjust the Z axis of the water actor in UE4.27?
