Forest River In UE5
Made a small section of river in Unreal Engine 5 and FluidNinja Live.
Houdini is used to modify the river mesh and calculate the collision areas.
River surface is exported in fbx format and collision areas are baked out in png files.
All dynamics are handled in UE5 with FluidNinja Live and Niagara particles, no flowmap, no vertex animation texture.
A version that includes waterfall can be found here:
The same approach for a stylized river can be found here:
