UE 5 Watersystem. Why is landscape deformation of the water system not enabled

Uploading: UE.png…

Obviously landscape deformation doesn’t work. WaterBrushManager is also not available
Although creating a new landscape can make the water system work. But I didn’t want to give up the landscape that was already sculpted

你好,我也出现这个问题了,您解决了吗

水未生效的地图内的地形开启选项了吗?

或许是,没有开启Landscape Edit Layers
