It worked great with the commandline version.

== Steps ==

1.) Create nCloth simulation
2.) Cache the nCloth (with nCloth cache)
3.) Cache with geometry cache
4.) convert the geometry cache (NOT nCloth cache) with formula below
5.) Use Kai's point cache addon to apply the cache inside XSI.

Formula
- - -
cacheFile -pc2 0 -pcf "[Path] / [File2beCreated.pc2]" -f "[Name
without extension on cached file]" -dir "[ Path to where the cachefile
resides ]";
- - -

ex:

The cache file from maya is created called "clothCache.mc" and
"clothCache.xml" (Maya automaticly creates two files). We will
generate a new file "called cloth.pc2"

In Maya's script window run:
cacheFile -pc2 0 -pcf "/tmp/cloth.pc2" -f "clothCache" -dir "/tmp/clothCache/";

When I was at CafeFX, I used that code quite a bit for this exact clothy

I forgot to mention however... that script is courtesy of Rob Tesdahl at
Cafe. Gotta give credit where credit is due.
