I need a fully-editable Niagara system that generates a realistic large-wave splash where fast-moving water meets a buildings/trees in my Unreal Engine 5.6 river level. The effect is strictly for environmental realism, so it must blend seamlessly with Fluid Flux). This is for use with sequencer/cinematics. You’ll start from a clean Niagara emitter (no legacy Cascade), drive the motion with GPU particles. Please keep all materials compatible with the UE 5.6 water plugin so I can instance the splash along the river spline without breaking flow direction or surface normals. Deliverables • .uasset Niagara system with clearly named emitters • Supporting textures, meshes, and materials (4K or less) • A demo level that shows the splash in a typical river bend, ready to migrate into my project • Short setup notes so I can tweak scale, timing, and LOD Acceptance If the splash reads naturally from both first-person shoreline view and a top-down camera at 60 fps on my reference RTX 5090 rig, the job is done.
