I get a better fit with some poke through.  Here is an example
of  a dress I did that had some poke through and still went
through the cloth room without any problem with the end
result being a nice, tight fit.

True :) I stated that there should be no poke through just because in many cases it freaks the calculation out, especially if you are changing the pose in the calculation and not only trying to fit a clothing item to a zeroed figure. It can slow the calculation down significantly also on weaker systems. But yes again, it is not a strict rule but rather an advice. The more important thing is not to allow the body intersect the cloth during the calculation, like having collars going into themselves when the pose requires arms to be down with cloth trapped inbetween. Or arms going through the body while changing pose in any point of the calculation. Hope it clears the things a bit :) Michal 4blueyes

I was mostly trying to let people know to not get too fanatical about poke-through,
that sometimes Poser can deal with a little bit.  I like to temp fate and give it a
little poke through when I run a simulation because it gives a tighter fit.
Basically  I try running the simulation and if it bombs, I give it a little less poke
through until it does run. 

Another thing people can do is make their character skinny in the first frame using x and z scale, and then restore the character's x and z to 100% in the final frame, so the character
sort of grows into the clothes rather than trying to expand the clothes to fit the
character.  Sometimes this works better.

Excellent advice about not letting the cloth get trapped or letting body parts go through
the body in an intermediate frame.  I have found that will crash or ruin a simulation
almost guaranteed.
