You can Ghost just about anything Hair, Cloth, Softbodies, etc

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.

-Brad

That's fantastic, cheers for the info, it certainly a feature that many of our
students (especially from a traditional animation background) have been crying
out for! Does it work as a script, an animation mixer option or an operator on
the characters mesh?

Yes, and it is tight!

I went through it with 1 of our animators and there was nothing that he wanted
to see that wasn't there - including IK/FK ghosting

There was a great trick discovered by someone on the beta programme were
animation ghosting allowed you to see the ghosting for a rigid body simulation
:-)

Hello,

Can anyone verify whether ghosting/onion skinning is available in XSI 4?

If not, can anyone recommend a method for ghosting animation of a character,
who's meshes have been enveloped to a rig.

Cheers!!!
