The attached picture is of V4 loaded with base morphs, morphs++ and A4 morphs.  All the morphs are zeroed except for the 'disgusted' morph which is set to 1.5.  As you can see, the eyes are totally out of whack.  Similar things happen when I use any dial that affects the eyes, everything else works fine as far as I have noticed.  This only happens when I have the A4 morphs loaded, the eye morphs work as expected when only the base and ++ packages are loaded.

I'm fairly certain that I have V4/A4 installed correctly, and I don't have this problem when I use the same morphs in poser.  Has anyone else come across this problem and/or know how to fix it?

This is a well known Aiko 4 bug in C6. The developers are fixing this for C7. The C7 Public Beta is suppose to be released next week, if all goes as planned.

I hate to harp on Daz because I really think they're a great company for the most part, but #1 on their "Top Reasons to Upgrade" on the Carrara homepage is "Complete Content Support."  Aiko 4 has been out how long now?  And M4 has problems, too.  I hope Daz gives better support for Carrara this time around to match its own marketing.

I can tell you M4, V4 and A4 work great in the C7 Public Beta right now.

You're right, I got the C7 beta and a lot of things are fixed.  It's a good program and I hope Daz will make bug fixes in a more timely manner from now on, especially when said bugs concern Daz's own flagship content.  Being able to handle cr2s was what sold me on Carrara in the first place.
