Quote - Which V4 version are you referring, base V4 or Weightmapped?  IIRC, the WM V4 does have incompatibility issues with some morphs, but not all.  I do agree with Fugazi1968 about pose limitations as dictated by the Limits On feature.

 

That's an interesting thought, I don't know how well morphs mix with the wm version.  I suspect to too well for JCMs that are created by posing the leg and fixing it.  But I've been pleasantly surprised before :)
