and floats. Select the object on the canvas or in the Models drawer first.

Controls:

• Rigid body: None passes through everything, Static is solid but never moves, and Dynamic falls, can be pushed and floats in water
• Extrudes: clears the procedural grass and trees from around the object
• Buoyancy (dynamic bodies only): how the object floats in beach, island or lake water. 0 sinks, 1 hangs where it is, 2 floats about half under, and higher values ride higher
• Shatter on impact (dynamic bodies only): breaks the object into pieces when it hits something fast enough

Good to know:

• A dynamic body only moves while room physics is on. When it is off, the tab offers Turn on room physics, the same switch as Enable physics runtime in the Interactions drawer's Physics tab
• A model collides as one box around all of it. Buoyancy is measured at that box's bottom corners, so a tall model such as a ship with masts usually needs a higher Buoyancy to sit at its waterline
• Place a floating object at or just above the water, so it does not drop in from a height
• The same controls appear in the Models drawer when an object is selected
