Im trying to save my Object Style Library from Invigorator classic plugin for AE to be used in ProAnimator plugin (AE)....any suggestions....I am able to save the library but i cannot load it into ProAnimator
The answer depends on which version of Classic you're running. I believe the file format for libraries has been changed between version 3.x and 4.x. The libraries in Invigorator 4.0x and beyond were rewritten to keep the file size down.
This may be a case where you need to upgrade Classic to get the compatibility back. Of course, you can simply make a note of the settings you want to replicate and build new materials in the ProAnimator Library.
