Why is my river deosn't moving?

[BRGEzeHulton]

I’m going to need more information:

• Video of the problem
• Unreal Engine Version
• The materials you’re using
• The details of the river

A suggestion, right click while you have the river selected, check these 3 options. Then try to arrange the splines.

• Visualize Water Velocity
• Visualize River Width
• Visualize Depth
  
  

I leave you a video that may help you
