Pick something to make.
Fire, water and things that fall apart. Each tutorial starts from a new project or one demo, and you shape the result by turning a few settings while it plays. Pick any of them, in any order.

Light a torch
A torch flame that burns off a small ball, made taller and warmer by you, and drawn the way a final render draws it.
- Add a ball
- Set it on fire
- See it rendered
- Make the flame yours

Shatter a ball into pieces
A ball that cracks into two dozen shards, which fly apart, tumble and settle on the floor, with a push you can turn up into an explosion.
- Add a ball
- Break it into pieces
- Turn up the push
- Make them bounce

Break a dam, then turn the water to mud
The first liquid to try, with foam where the water churns: a column of water lets go, slams the far wall and sloshes back. Then you make it thick and slow, and give it more water.
- Open the demo
- Watch it slosh
- Make it thick
- Add more water

Drip honey that piles up as it lands
A block of honey let go above a small tank. It stretches into a slow drip and spreads into a heavy amber pile, dropped from the height you choose.
- Open the demo
- Watch it pile up
- Make it thicker
- Drop it from higher

Swirl a pool into a whirlpool
A tank of water stirred with no paddle. Gravity leans around in a circle, the water banks into a spin, and you make it swirl faster and splash higher.
- Open the demo
- Find the tilt
- Stir it faster
- Lean it harder
Pull these apart.
