I render out as tiff. I started that back with Poser4. I rarely use 'render as black', I simply change the background color in the studio to black and render. I've had no problems with bringing these tiffs from P6 into Paintshop and using the alpha chanel to delete the black background. Try changing the color of your studio's background to black rather than using the 'render as black' option and you might loose your problem.

I did not know that ping format has an alpha channel. The only other format that I found with alpha channel is Poser besides tiff was targa.
