Hey all. Trying to create rivers on my landscape using splines and planes. However, I am having difficulty in figuring out how to add depth to these planes as I have no Z axis to play with. Additionally, I seem to have trouble with ‘floating’ rovers. (see video)
Can anyone help with these issues?
Thanks in advance.
The easiest way to do it is to have the spline which defines the river also Sculpt the landscape.
There is a blueprint node for that, which you should hook into a bluetility event to call from the editor.
For rivers with a deep depth you may want to duplicate the spline and shift it down on Z as a whole about 1m, then manage individual segments to sculpt deeper areas.
The water mesh is also important and likely needs to be far wider than the river to avoid issues.
Id say double the river width is a good starting point for it.
Additionally, if you use the engine’s built in water mess, you can use the builtin river thing… it does what you need to create manually with a bunch more options (and thefore low performance) for you.
Sadly, the built-in water tools don’t work with an imported heightmap.
I’ll toy around with the other suggestions tho… thanks
