alpha channel in turntable plus

hi all,
I have a little problem using the turntable plus plug in on zb 4R6.
When I click on the best preview render in the turntable plus options and launch my render, even if I check the alpha case in order to calculate the alpha, it seems not to render it as a separate image sequence, and it just renders one sequence of image with a black background.
Obviously importing these images in photoshop or after effect reveals that the black colour around my character is not an alpha.

If I don`t check the best preview button, the alpha is calculated as a proper image sequence, but the aliasing all around the character is a problem…unless calculating veeeery big images and reduce their size…

did someone have the same problem?
any solution?

thanks a lot

thanks a lot,

Is it normal that the beauty images sequenge still has a black colour all around the character? Shouldn`t it have the background colour that I choose in the scene?
thanks again

The beauty image exported through the render passes is like that because it is assumed you will be using it (along with the mask pass) to composite a background of your choice. If you want the ZBrush background then you can use the main document, exporting through the Document palette.
