I'm not sure if this is an AL problem or a P8 problem:
Certain mat poses (pz2 files) don't apply in P8 when loaded via AL. They work perfectly well in P7 (loaded via AL) and they work when loaded directly in P8 from the Poser library.
Some examples for those non-working mat poses are DAZ character sets for V4, like "Modern Muses: Zoe" or "Glymmer". There may be others, but I haven't tested all my files yet.
I compared these files with some which work, and there weren't any real differences. I have no idea why some work and some don't.
what version of AL are you using?
what's the path to the files?
does loading them work if you press shift while double clicking the mat pose?
Sorry, false alarm! :-[
I've installed the latest release now and now it works.
(Should've checked earlier, just didn't think that there was already a new one available...)
Sorry again!
oh, I'm glad that it's not a new bug :-)
