You can do some great PSP tubes from your Poser characters. Simply save as a .tiff file in Poser (important to do it in Poser cause it won't work after the fact). Open the .tiff file in PSP, Select, Load from alpha. That will put the marching ants around your image, then you can copy and paste into a new transparent canvas. There wont be any jaggies and none of the background color you use will be there :)
