i had the same problem. open photshop, duplicate your render layer and delete to original so it is not locked as the background. then go to your channels tab, and ctrl-click the alpha layer. then select inverse (ctrl-shift-i) and then delete. it will get rid of the background leaving only your render. thats the only way i found to work :blink: and it cuts it out perfectly.

Theres a cleaner way to do this...check my tutorial on Chroma key setup here
If you do a black background and then cut it out in ps you are likely to cut out anything in your render that might be black or close to black. By making a solid color background when you render you get a nice clean color that you can select and get rid of without worry of cutting out some of your render. You can set it to any color you want that is very different from your rendered materials. And make sure you set the variables to make it a composit background so it is a flat color and not recieving any lights or shadows that could complicate the cutting out. You will have a perfect flat color that you can use the magic wand on in photoshop and then do and inverse select to select your object.

EDIT- ok here is a step by step video on how to do this Cut out your background renders

not if you do it that way ^
im not talking about cropping it by using magic eraser or whatever. all you have to do is ctrl click the alpha channel and select inverse and delete. it doesnt delete anything because of colors.

It will delete part of your image if you image has any black in it. Try to do your alpha selection on this render and see what happens... Posted Image
It's not going to work. If you start getting into alpha channels you will pick up part of the render when it shouldn't and you will lose a large portion of the two boxes. And what I said above in the tut isn't cropping anything.. Its using the magic WAND to select the background, which is rendered in a very different color from anything you use in your object materials and thus avoid any bleeding over that you would get from using alpha channel selections. Use the compositing render method from the tut and you would end up with this:

which takes all of 2 seconds to remove the background from and gives you perfectly clean cut edges.

It must be a easier way to do that.. not that this aint easy.. I just mean the Alpha channel in C4D must work in some way.. or some settings in PSPCS must be made. When I render my piece I get black background in PSPCS.. But if I import save file into Flash MX 2004 it suddenly goes away.. Shazaaam! No background. So according to me its PSPCS that needs to be configured in some way.

PSPCS- Do you mean PSCS (photoshop cs) or PSP(paint shop pro)? Yes there is a way to get the alpha channels to work, FS even did a very straight forward tut on it, but it seems a lot of people here just cant get it to work so that's why I wrote the tut for this method. At least if the can't get it to work like it's suppose to they can still have a way to get what they want.

Sorry for bumping this old topic.
I've got C4D XL7 and to get transparant bg in ps7. Check both Alpha Channel and Seperate Channel. this works fine.
I firts couldnt get it to work with just Alpha Channel, but with Seperate Alpha checked too, it works fine.

There is a problem exporting it to photoshop CS tho.

Allow me to assist you. My name is Skitzo and I'm new here.

To get a transparent background on PS CS do the following.

1. Go to "Render Settings..."
2. Click "Save"
3. Set the Format as: "TARGA"
4. Check the "Alpha Channel" box
5. UNCHECK THE "24-BIT DITHERING" box
6. Click "Output"
7. Set that crap to whatever you want.
8. Close the Render Settings window
9. Go to "Render To Picture Viewer"
10. When it's done rendering go to File>Save Picture as..
11. Make sure the Format is set to TARGA
12. Make sure the "Alpha Channel" box is checked.
13. And save that crap whereever you want.

TIME FOR PHOTOSHOP CS BABY.

14. Open your whatever crap .tga
15. In the "Layers" window, click the "Channels" Tab
16. If you did everything you were supposed to in C4D correctly, u should see the different channels.
17. Here's a list of each channel you should see:
RGB
Red
Green
Blue
Alpha1

18. Press and Hold CRTL+A and while HOLDING THAT DOWN, CLICK EACH INDIVISUAL CHANNEL.
19. Release your hold and click back to the "Layers" tab.
20. Right click the single layer that is there and choose "Layer via Copy..."
21. A layer should appear above it with a PERFECTLY PRECISE TRANSPARENT BG'ed Render Cut with the finest blades of the virtual world. Yes baby... it's that good.

That's it.

MAIN POINT:
There was a certain attribute that PS CS differenced from PS 7. That was the 24-Bit dithering option in Cinema4D. It's not their fault. Adobe has nothing to do with Maxon.

If you need any assistance in doing this, feel free to contact me at my messengers:
