Questions about using alpha image
I am new to Cinema 4 D (I have Studio Bundle R10 on Mac) and I have run into some trouble with my material texture.
I have a lot of experience with alphas in other applications so i have made a fairly clean version in Photoshop (maybe I am not). I brought it in as a native file (PSD) with a normal alpha, I did not create a channel alpha. My first question is… what is the best advice on what file type to bring in? This worked more or less but is there a preferred type?
The first trouble I had was a thin white halo along the edge of the cutout image. I do not encounter this very often but have dealt with it before by laying a thin dark line at the edge. I would prefer to avoid this as it more than likely look cartoony in this case. The next question, is there a setting that I am missing to eliminate this artifact?
Also, I do not want the cube to be visible at all but I am getting a thin line at its edge. I created a completely transparent material and laid it on below the guy but I am still

-put the psd in the alpha channel too. (tiff or psd both good, both same rules)
-the thin line on the edge is usually caused by antialiasing and that’s a whole subject in itself
-cube? -
in c4d 10 it seems to work cleanly by just putting the same photoshop cutout/still in the color and the alpha channel as brian mentioned. i had problems with this alpha fringe in C4D 9 with some photohop art. maybe check this:

Thanks guys. Oddly part of it went away on the edge of alpha when I applied a bump.
Stillgetting a bit at top edge of ‘portrait’ object, which I have now changed to a plane object.
Lots of settings in anti alias any thoughts on which to goose to remove the line?
