I can't I disable collisions between two bodies.
If your objects don't appear in the
Define Collisions dialog on page 4092, make
sure you've added the two bodies to a collection; only objects in collections
are shown in that dialog.
Rigid bodies don't sink/don't float in the water.
Objects sink or float depending on their density and the density of the water.
You define water density explicitly in the
Water space warp on page 4074. The
density of a rigid body is defined as its mass divided by its volume.
■ Check that your objects have real-world sizes (or adjust the
world scale on
page 4087) and
masses on page 3911.
If your bodies still don't sink enough for your liking, try the following:
■ Increase the mass of the bodies.
■ Decrease the density of the water.
■ Decrease the viscosity of the water, this can slow down the sinking.
Follow the opposite steps if you're trying to make your objects float more.
Water doesn't ripple enough
You can either increase the Max Ripple value in the
Water space warp on page
4075, or you can scale the effect of the space warp on a particular object that
you've bound to the space warp by modifying the Scale Strength value in the
Water world-space modifier on page 4078. The first option (increasing the Max
Ripple value) is preferable, but you need to re-create the animation in order
to see the effect. The second option (increase the Scale Strength parameter in
the modifier) affects only the object bound to the Water space warp. It can
thus produce inconsistent results if you have objects floating in the water,
because they won't be affected by the change.
I can't see any stored collisions.
Make sure you've set reactor to
store collisions on page 4019 during the
simulation. Collisions are stored only for rigid bodies; not for Cloth, Soft
Bodies, or Rope.
