Move geometry with the force of a fluid

You can move NURBS or polygonal geometry with the force of a fluid by making the geometry an active rigid body.

To move geometry with the force of a fluid

1. Create a dynamic fluid. For details, see Dynamic Grids.
2. Move the geometry inside the fluid container. The geometry must be inside the container to be affected by the fluid.
3. Make the geometry an active rigid body (select the geometry and select Soft/Rigid Bodies > Create Active Rigid Body. For more information on creating rigid bodies, see Maya Classic Dynamics.
4. In the rigidBodyAttribute Editor, under Performance Attributes, set the Apply Force At to centerOfMass or verticesOrCVs depending on how you want the force of the fluid to affect the rigid body.
5. Select both the fluid container and the geometry (order doesn't matter).
6. Select Fields > Affect Selected Object(s).
7. Play the simulation using the playback controls at the bottom of the Maya window.
8. Modify the effect, as required:
