Carrara thumbs, huh ?
The problem is that I have 95% of the code to read them (which eovia kindly gave to me) but the code was incomplete and I absolutely don't know how to start.
I've got so many side projects with P3dO that I don't insist when things take too much time. So you know if you dearly want those thumbs ask me again and again and it'll be done.
