I am pretty sure that i read that poser allows you to render with a transparent background is this true and if so can i do it with poser 6?
If yes....HOW?

Save the image to either .tif or .png, and it will have an alpha mask included.

Caveat on that: once you get the image in Photoshop, decrease the alpha by 1 pixel to avoid fringing.

And remember that (on a Mac anyway) png files have no alphas, only tifs.

ok...i don't have photoshop...only Paint shop pro...same deal?

Your best bet then is to render in png format, but do so three times the size you want for final.

Thanks you for this tip !!!!

Render your image on a black background.  Then save as a .png file. The .png file is considered "lossless" so your image isn't degraded.  When you open it in a program that supports transparent alpha channels, the image has no background.

I know that some save it as a .tiff image. But when you do that you have to appy the image to itself as a mask in your graphic program to get rid of the background.  Saving as a .png doesn't require you to do that.

I don't think you need to do this in P7.

No, you do. I still have the same problem with that one-pixel fringe. Drives me crazy if I go directly from render size to final image size.

Sean - I'd say to render it four times the size but that's simply because resizing generally is more accurate in powers of two.  But, definitely render as large as possible.

Yeah, my rule of thumb is about 3 to 4, but I try not to get too crazy about it unless it's for print.

As Acadia said, set your render settings to render over black. That's supposed to make the PNG alpha channel accurate. See link for details. It may still be different on Macs, of course...

It sounds like premultiplied vs straight alpha issue. Maybe this helps?

It doesnt look quite the same, but I'll give it a shot. Thanks for the link.

Don't know if anyone knows this. Gimp will import .tiff with perfect transparent background and it's free. Render with background Black and save as .tiff. If I have an image with many layers, I stack it all in gimp first and save that out as PSD. I can then use it in my Painter or PSP. I don't have PS, to expensive for my wallet.
