Problem using Duplicate/Instantiate tool

[mcewan7]

I'm working through the Digital Tutors Introduction to XSI videos and I'm on the modeling section and making some fan blades for the jet engine.

I have my blade, then I duplicate/instatiate 12 degrees around Z 29 times. So I get a nice duplication of 30 fan blades in a circle. This all works great. The problem comes if I close and save the file, when I open it up again, there what appears to be only 1 fan blade. On closer inspection all 30 fan blades are occupying the same space. They have lost the 12 degree spacing around Z information.

Is there something I need to do to get the fan blades to stay fixed in their positions?

I just opened the base scene again, duplicated the fan blade and then set a key for frame one with the blades in their correct position. Got the same problem again.

I've also noticed that after running the duplicate instanciate tool, if I then click on any other frame they all return to the position of the parent. Even if I set a keyframe.

Anyone have any ideas?

You must FREEZE your duplications to unparent
from original source. FREEZE button is bottom right on your layout. :) try

I remember clicking the freeze button to see if this solved my probelm and it did not appear to. But now that I think about it, I may not have had anything selected at the time, and I bet you must have your object selected that you want to freeze the stack on.

Quick question, if I click freeze for these fan blades, do I need to have all 30 selected or just the 29 instances. I'm guessing its all 30.

If it does turn out that the freeze button is the step I need to take, is this on the video? If so I must have missed it.

Hey thanks, I got it sorted now. It was something to do with a key, I just removed all animation and now it works as expected. I shall chalk this one up as a school boy error ;)
