Built for believable water
Automatic obstacle foam
Foam is generated automatically wherever the flow meets rocks and obstacles.
Realistic water shader
Distortion, reflection and caustics for a convincing translucent surface.
Spline-based river tool
Draw a spline and the river is built and flow-mapped along it.
Spline-based cascade tool
Create flowing cascades and waterfalls with the same spline workflow.
Flow visualization
Linear and turbulent flow visualization to read the water at a glance.
Angle-based flow material
The material reacts to river angle for natural rapids and calm stretches.
Buoyancy interactions
Physical objects interact with the river surface for floating and bobbing.
Custom foam & opacity painting
Automatic and hand-painted foam and opacity control via vertex paint.
Photo-scanned forest assets
High-quality photo-scanned trees, grass, stones and props to dress the scene.
UV distortion & warping
Automatic river UV distortion and warping with object detection.
Parametric wet stones
Stones blend wet and dry along the waterline, fully parametric.
Flow displacement animation
Height shifts and displacement driven by obstacles and river angle.
