Alpha Channels help

Hi Cyber friends!


I have problems with blending 3D pictures(w/ black blackground) into another 2D picture with alpha channels in that 3D picture. Everytime I try to copy and paste under LOAD Selection, i get the 3D picture stuck with the black background or totally white with no picture when paste onto the 2D picture. How do i rectiy this problem? I want to paste the 3D picture(minus the black background) to blend into 2D picture. Do I have to play around with the channels?
need Help on alpha channels and blending. Thanks

does your 3d picture have its own alpha channel? if it does. go into Channels. and command/control+click on the alpha layer
and then you can drag the image with its alpha selected.

Hi!

What if my 3D picture does not have Alpha channel? Is it possible to paste the 3D picture without the background(black) accompanied with it? Is there anyway I can separate the background of the 3D picture to paste it on the 2D picture? Like some explode command or something?

3D Studio Max I know allows you to save an alpha channel when you save off an image as a TIFF.

If your render did not include an alpha channel, the only way to get the image out of the background and leave transparent edges is to cut/mask it out using photoshop's masking tools.

Max renders Targas as well. and they keep alpha channels as well.
few questions.
1. Are these 3D models you made?
2. what is an explode command?
