XSI Constraints Problem 2005-04-15 - By Robert Moodie
Back
This wouldn't happen to be either an underwater or 'electrical' sequence would
it???
Anyways, could you check the constraints and see if they have been duplicated
on save/re-open?
There has been a problem with constraining objects *within* a reference model
to objects that are not within the same model space.
We had it here recently and we were ending up with a gazillion of the same
constraints on the object that should have had only 1.
Another little check would be to turn on 'Relations' in the visibility options
of the viewport to see what the object in question is connected to.
Let me know...

--A co-worker asked me to foward this to the list--
Hey,
I'm having to animate on a project using XSI, but this is the first time I've
used the program. I've run into a very strange problem which maybe someone has
seen before and knows the solution...I hope.
Here's the situation. I have several creatures attacking a character, about
10. Everything is a refrence model, so there is one main character model and
ten creatures from the same model. Each model is attached to a null so I can
globally place them. In a good setup, this null or control would have been in
the model, but it was not, so I added something I could use and adjust. I have
no control over the models btw.
Some of the creatures need to bite and attach themselves to the character,
inherting the characters motion since he is flailing around. To do this, I am
using a pose constraint on the creatures and blending it to zero when they are
off, and one when they are on. The rest are just moving about and attacking.
It all appears to work fine. I even make playblasts with the animation
showing them jumping and attaching themselves. In other words, it works, there
are no problems. So I save and keep going. However, when I reopen the progam
and load the scene back up, the creatures that were constrained are not in the
correct location. It is as if they have been offset. They still have the
animated constraint, but they are not in the right location. Moving the global
placer null has no effect for the constrained section either.
Here's the kicker. If I delete the constraint, reposition the global placer,
do not reapply the constraint, save, close program and reopen reload, the
creature will not be where I put him. Every other creature is in the right
location, the ones who have never been constrained, but this one seems to be
permanently broken. He's not even constrained anymore but he is still being
offset!
I can fix this all I want, and it will look fine in the program. But once I
close the scene and reopen it, it will be broken. This is very frustrating
because I have no idea how to fix it or why it is even doing this.
The refrence models have not changed, they are the same files as when I
started.
Any thoughts or insights would be greatly appreciated.
