A block is born each frame for the first 60 frames, 2.5 m up, turned at random. Rigid Body makes each one a solid box: it tumbles, knocks into the others and stacks, with the weight of wood (500 kg/m³). The particles show as the 20 cm Block shape, painted by Block Paint in each particle's colour: orange, with some difference between blocks.
Try these first
- Edit FlowBlocksBirthEnd: more frames, more blocks.
- Edit FlowBlocksRigid BodyFriction: low and they slide off each other; high and they stack.
- Edit FlowBlocksRigid BodyBounce: a little for wood, more for rubber.
Make it yours
- Your own shape. Put your model in the Shapes collection in place of the Block (or beside it, with a Shape operator to mix them), and pick how Rigid Body holds it in the operator's Shape: Box (fastest, for bricks and crates), Ball (rolls), Hull (the shape wrapped tight, for rocks) or Concave (hollows and all, for cups and bowls; slower).
- Heavier or lighter. Density in kg/m³: about 2,500 for stone, 7,850 for steel. A heavy body pushes light ones aside.
- Things to land on. Name an object in Collide, or add one more Collide.
