Quick and dirty way to make the cloth huge an object is this.
1)Create the cloth smaller then the object you want to put cloth on
2)apply syflex and all attributes
3)scale the cloth object bigger then your collision objects (don’t keyframe)
4)hit play and it will snap back where it should be

Subject: "Rescale" on syflex in XSI

I'm doing cloth sim on a character now that needs a lot of tension in
the cloth (wings). I've noticed several Maya Syflex tutorials mention
a "rescale" attribute that lets the cloth tend to shrink or expand.
That is, it seems to scale the rest length on the springs.

This is completely necessary for what I am doing, but I can't seem to
find this setting in XSI Syflex. I don't even see a parameter that
stores spring rest length, it seems to be internal to the operator.

As a result I am using XSI cloth, which has this option in "tension".
It is working well, but in the future XSI cloth might not cut it. Also
we have some scripts that set the syflex's initial state from another
mesh, it would be nice to reset the spring rest length as well.

I don't think I could implement this as a custom force since it would
fight the rest length and might result in instability but perhaps I am
wrong. Thoughts?
