Rita, if I'm following correctly, you are saving your rendered antialias image in Poser and then bringing it into PSP where you want the background (that was created in Poser?) to be transparent? Why don't you create your image in Poser but then make the background there "NOT display" if you want to use one to pose your figure to begin with--go to Display and 'clear background' (OR don't add one to begin with--just make the background white). This way you can save your 'figure' as a .tiff, go to PSP and then to selections where you 'select from alpha channel' and then copy and paste as a new layer over your background. That way you can try out as many backgrounds as you wish. I just tried it with one of my saved .tiffs and I didn't have any 'jaggies' at all on that one. What I see in PSP is my figure against a white background, then the alpha channel (mask) selects my figure for an easy copy and paste. Is this what you are doing and you are still getting jaggies? If you are saving a Poser image with a background and then trying to 'delete' or make that background transparent after bringing it into PSP, I don't know. (I tried saving an image with BG in Poser and then selecting--that worked okay for me too). Well, just tried it both ways and I'm not getting jaggies either way and adding the figure over the image in PSP as opposed to rendering it with the background pic in Poser doesn't look appreciably different to me. Why don't you post a pic showing us what you mean--one rendered in Poser and then what you are getting in PSP. That would be helpful. Diane B
