Is there something like trajectories in 3ds Max in XSI?
I'm animating something that needs smooth circular motion and I need to see it in the process.
Thank you.

You can use ghosting.

Well I know about ghosting but it doesn't give me the idea of how smooth is the animation.
I need a line showing the trajectory and it shows objects.

You can plot a curve from you animations.
Just select your object then do tools/plot/curve

Thanks
it works but do I have to do it every time I change the animation?
Because the curve isn't changing when I change the animation.

YES, you should
But if you press the Plot button with middle mouse button it will do your last command so it's quite fast.

Hehe
here are some lines from Xsi documentation:

Selecting the Ghosting Display Type
You can determines the appearance of the ghosted shapes for each animated object. By default, the object’s geometry is displayed as the ghost.

The display types use the current settings as defined in the Camera Display property editor, including fading and whether ghosts are drawn on top of the object.

To select the ghost display type

1. In an explorer, click the Visibility icon for an object to open its Visibility property editor.

2. In the Animation area, select an option from the Ghost Type list: Object, Point, Pose, Velocity, or Trail.

Trail is exaclty what you need.

So what is the conclusion?
the conclusion is RTFM

Wow! Xsi is much cooler then I thought!
Many thanks!
Wow!!!
