There is a way to convert V3 face expressions to V4 face expressions  ?

I have the same problem with some M3 body poses wich doesen't work with M4

I'm using P8 and i only have V4 and all her morphs....

Many thanks....

There is a Universal Pose feature built-in to P8 which can serve you for applying body poses.  You can activate the feature in General Preferences and any pose that you save back into your library will become a universal pose.  IIRC, using the double check folder in the library under the Poses Category will apply universal poses also.  I have never tried it with expressions, so I couldn't say if that will work the same way.

Universal Pose does not apply to Expressions, the double check mark option does not appear.

Expressions use heavily the figure specific expression morphs, which have different names and functions from figure to figure.  AFAIK, there is no method to convert or use them satisfactorily

As I know,expressions are morphs, and morphs only can apply on the original mesh.

V3 and V4 are two different meshs,so I think the expressions cannot convert from one to another.

In instances where you attempt to apply an expression to a mismatched mesh, you will get a warning and Poser may try to inject the morph.  However, the results may not be pleasing.

You might want to look thru this topic. Cage wrote a script to do what you're asking about.
