I seem to remember that masking in 5.1 kept the background from moving during 2D puppetry.   But in trying this with 8.1, it instead masks OUT (turns white) the entire background which is not what I'm wanting.

Would anyone be able to tell me what I'm missing?    I just want the background frozen during facial animations...

On more questions.   Can custom created heads be shared with other users ?   If so, what is the best way to do so?

Thanks
