Liquid
A dam breaking. A column of water falls and runs along a glass tank, climbing the far wall.

What it makes
- Birth: Mode Fill, Object Water Column
- Gravity
- Liquid: Spacing 0.03
- Collide: Object Water Tank, Ground On, Bounce 0, Friction 0
The tank is 1.6 m long, 0.6 m wide and 0.9 m tall, open at the top, made of glass and shown as wire in the viewport. The water starts as a column 40 cm deep at one end (Water Column, shown as wire and not rendered). On the first frame Birth fills it with particles 3 cm apart, the Liquid operator makes them water, and gravity drops them: the column collapses and runs along the tank.
The bake adds Water Liquid: the water's surface as a mesh, made fresh each frame and smooth shaded, in the VecFlow Water material. The particles themselves aren't shown: the liquid shows only as its surface.
Try these first
- Edit FlowWaterLiquidSpacing: how far apart the particles are. Half the spacing is eight times the particles and finer splashes, and a much slower bake.
- Detail: how fine the surface mesh is. No new simulation, but the surface is made again.
- Water Colour in the Render Look: tint the water, no new bake.
Make it yours
- Your own container and water. Use any closed mesh for the water (it's the Birth's Object), and any mesh for the tank (the Collide's Object). Or start from Fill With Water.
- A tap. Birth's Fill with Stop keeps the mesh full until then: water pours out of it as an inflow.
- Spray and foam. Add a Whitewater operator: spray, foam and bubbles where the water crashes, each sent to an event of its own.
