Water simulator FAQ
How does the water simulator work?
The water is made of thousands of particles that keep the same spacing, so they behave like a liquid that cannot be squeezed: they fall, splash, slosh and level out.
How do I tilt the water?
Use the tilt buttons under the canvas, the Tilt slider in Settings or the left and right arrow keys. The small circle in the corner shows which way is down.
Can I make the water thicker?
Yes. Raise Thickness for honey-like flow and Cohesion to make it hold together in blobs; Lava and Slime colours suit them.
How many particles can it handle?
From 500 up to 6,000. 2,500 runs smoothly on most laptops and phones; lower the count if it slows down.
Is the water simulator free?
Yes. No sign-up and no watermark on screenshots or videos.
