Sketch#49 - Cliffside Falls

[wijobu]

Started by assembling a few Megascans assets in UE5.

[wijobu]

Merged and downres’d the results in Houdini.

I used curves to draw each water stream, and swept some geometry over each curve.

[wijobu]

The UV’s of each stream are normalized along their length, and velocities are painted onto the geo to prepare flowmaps.

[wijobu]

Each stream’s UV’s are packed into a single 3x3 tile to bake all (9) streams into a single asset with a single flowmap.

[wijobu]

The lake surface gets exported with a map to control the intensity of turbulence, as it fades off from the stream collisions.

[wijobu]

I setup a quick FLIP fluid sim, and rendered the animation out to a spritesheet. The spritesheets for splashes and mist were used with UE5 Niagara systems.

[wijobu]

Refractive foamy water shader.

[wijobu]

Almost forgot! I made a very quick, very basic little procedural bridge tool.

Lot of cool things you put together there! I’m a fan of the thinner broken up waterfalls. Its tricky to use some of those sprites because they need to be tuned after the lighting is done, but overall great sketch.
