Set Geometry reaction


This reaction swaps the geometry of one object for another.

For example, swap from a cube to a sphere or an ant to an elephant. The two objects do not have to have the same number of points. In many cases, you hide the second object.

Note: This is different from a Shape animation, where a shape changes over time, or a Switch Shape animation, where a shape changes as you move the object.

To create a Set Geometry reaction:
  1. In the World Explorer, expand the two objects. For example, to change a cube into a sphere, expand the cube and the sphere.
  2. Multi-select the objects. First select the object whose shape will change (Cube), then Shift-select the geometry of the second object (SphereGeometry).
  3. Choose Interactions > Reactions > Set Geometry.
  4. Link the reaction to a sensor.
  5. When the reaction is triggered, the sphere becomes a cube.
