Water Simulation
The reactor Water object allows you to simulate the behavior of a water surface.
Objects can interact with the water in physically realistic ways, creating waves
and ripples. reactor calculates a buoyancy value for any objects that fall into
the water using their mass and size, so that some objects sink and others float.
You can even change the density of a water object, which affects how objects
float in it.
Water in reactor is a
space warp on page 8132 that is simulated as water. Space
warps don't render, so you need to provide reactor with a geometrical
representation of the water if you want it to appear in your final animation.
You do this by binding a plane or other geometry to the space warp. Note
that a representation of the water still appears in the Preview Window even
if you haven't done this.
