actually the instructions in that link aren't right.
here is what you need to do.

Creating Link Libraries and IPB Prep Pose.

1 In Poser first make sure that you turn off save external Binary morphs in your preferences.

2 Load V4.2

3 inject all morphs

4 Save back to library

 

5 In IPB Open saved V4

6 Select Create New

7 Fill in dialog

8 When Choose a file comes up go to !DAZ/Victoria 4 folder and select one of the pz2 files in that folder.

9 This is the PIA part, Select all the expression morphs.

10 You are done creating a link library but you want to do one more thing create an IPB prep file. Do this by selecting Tools create IPB Prep Pose. The pose will be created and to save it simply select your new Victora4.2 and hit save.

 

OK this is done, you never have to do this again unless you install new injection morphs which you want to use in your characters.

 

Creating V4 character.

 

1 create your character with Victoria 4

2 apply your IPB Prep pose, your character will disappear but that's OK, the dial settings are still there just the deltas have been removed in order to speed up the IPB process.

3 save your character back to the library.

4Open your character in IPB

5 Select your Victoria4.2 prep file.

6 For settings I use the defaults, except also check Exclude Zeroed Channels, and also I tend to use Selected actors only and select the Head and Body, since I don't tend to set morphs in the other body parts. This tends to clear out the jcms which weren't zeroed.

7 Process Options.

8 Save Injection pose.
