@ ThrommArcadia,

Quote - I liked that with Poser 5 you could render over a background and still get an alpha channel, this allowed for some very nice postwork.  Unfortunately they purposefully changed that in Poser 6.

Well I seem to be living in a separate reality here. Must be something in the water.

I can render over a background and get an alpha channel in P6. This works for me with TIF, PGN, and PSD.

@ bagginsbill,

Quote - It looks to me like the render was already pre-multiplied, but PSP is not taking that into account, and is multiplying the fringe pixels with the alpha channel. This results in double darkening of the skin color.

Some how I doubt this. If I render over black i get a fringe that tends towards black, if If I render over white I get a fringe that tends towards white, and if I render over green I get a fringe that tends towards green. It looks like the alpha channel is anti-aliased with the background colour, no matter which colour is used, even black. Actually this is what I would have expected, before I read the posts by ghonma and bagginsbill.

If there is a way to do a fringe-less comp in PSP 5 (or 7) I would sure like to know how, it could handy. But at the moment this is still not working for me. any further thoughts/suggestions?
