Perhaps Dark_Whisper will develop a LaRoo plugin for the Universal Texture Convertor. Although, frankly, I'm hoping for Posette/P4 Male support next, after Mike 3.

Does your problem with Koshini have something to do with the ears? Her ears are posable body parts. The CR2 won't load the ear geometry unless you've added ear bones to the figure's skeletal structure.

I've been following Yamato's tutorial also, and transplanted the Millennium Cat's head onto Victoria.
