Ghosting in XSI 4.0 is very powerful and incredibly versatile. It's both
a camera option and a per object option.

Camera Settings:
- You can choose which cameras show ghosting and how they display per
camera.
- Each camera can have a unique setting for ghosting colors, trail
length, and fading effects.
- Each camera can have a unique setting for whether to show per frame
ghosting, ghosting keyframes, or both.

Per Object Settings:
- Ghosting per object is treated as a visibility property, alongside
view and render visibility.
- Each object's ghost can have a unique graphical representation:
-Object (Ghosts the entire object geometry)
-Point (Ghosts just a position marker, no rot info)
-Pose (Ghosts the object's center)
-Velocity (Ghosts a vector representation of the change in velocity
over time. This one is incredibly powerful for checking animation
smoothness!)
-Trail (Creates a curve path the ghosted object is traveling on)

There are so many options, and it's tied into the architecture at a very
core level, so a lot of really cool tricks are out there just waiting to
be discovered.

As has already been mentioned, someone figured out that you could turn
on ghosting on objects that are being run through Rigid Body Dynamics.
Depending on the complexity of the sim and the number of objects
involved, you can use ghosting to show a realtime preview of how the
simulation will turn out! Here's an example of what you can do with this:

Ghost your RBD object well into the future, then open up the various RBD
properties. In realtime, you can tweak the elasticity and friction
parameters and see the sim path of your object update the size of its
bounces!

You could add wind, turbulence, tweak gravity, etc... all in real time
in order to adjust the results of the simulations.

No more tweaking values and running sims 100 times until your ball makes
it through the hoop. Ghost it into the future, then adjust your sliders
until the ghost shows the ball going where you want it to.

Hello,<o:p></o:p>
<o:p> </o:p>
Can anyone
verify whether ghosting/onion skinning is available in XSI 4?  <o:p></o:p>
If not, can
anyone recommend a method for ghosting animation of a character, who's
meshes have been enveloped to a rig.<o:p></o:p>
