Lately I've been cracking open these Poser files (.cr2, .pz2, etc) just to try and figure out what's going on inside them, and I've gotta tell you - it's ugly in there.

When I saw this thread I thought I'd take a look inside some .fc2 files, and it's not any prettier there. There are so many inconsistencies, errors, and different approaches it's amazing they work as well as they do.

Here's what I've found out so far. As xpdev noticed some of these fc2 files change not just the expression but set the face back to Vicky (or whatever the base model is). This is just plain wrong and the vendors should correct them. An fc2 file that works as it should will be about 9K in size. If you see one that's around 28 - 33K you know it will set the face back to Vicky.

ErickL88's approach will work, but it's very cumbersome and prone to error. You have to go down the entire list of morph channels and set each one on or off. There's no way to select a range and set them all at once. That's not Eric's fault of course; it's just the way Poser works.

The better approach is to use gsayer's FC2FIX tool (thanks for the tip, cspear) which runs through fc2 files and drops any morph channels that aren't considered real expressions. The real expressions are maintained in a txt file called acceptable.txt and the user can modify it to suite their own purposes.

Finally, I noticed that some expression packages were actually in a pz2 format which is for the entire body, not just expressions. The FC2FIX tool can't fix those. I think the reason some vendors do this is because sometimes they bring the tongue and perhaps the neck into an expression, and I guess those are outside the scope of a fc2 file.

So, there you go. Hope it helped.
