Chunk 3D is a free character from Meshbox Design. As of this writing, it includes a DAZ Mimic DMC file. How does it work?
DAZ Mimic is a special tool for speech usable in some versions of DAZ Studio and Renderosity Poser. A tech article is available on the DAZ3D website.
The DMC file only works if all the morph information is within the cr2 file is not not using pmd files.
Ensure this is true by going to Poser General Preferences Dialog > Misc Tab and uncheck Use external binary morph targets.
