wow, i had no idea this was possible in povray. call me a slacker for not

  The real fun begins when you render several images of different objects
against a transparent background and then open the images in an image
manipulation program (such as gimp or photoshop) to different layers
and move them around.

Yes, of course Warp I've read it.

Well, I've put the +UA in the box, in the Pov-Ray i can see the background
transparent, but when I see the BMP file in the CorelDraw the background it
isn't transparent, it's black.
Ross's says:
" Note that in order for POV-Ray to be able to save the alpha channel to the
image file, you have to use a format which supports alpha channel, such as
for example PNG."
Maybe that's my problem. I'm going to read the help file again, Warp.

Best regards,
Oleguer

I think the problem is with the output file.
==============================
Input_File_Name=myinput.pov
Output_File_Name=myoutput.tga
==============================
Well, I don't undersant how can I convert the files. In the Pov-Ray windows
code?

I have read this: "In addition to support for variable bit-depths, alpha
channel, and grayscale formats, PNG files also store the Display_Gamma value
so the image displays properly on all systems (see section "Display Hardware
Settings"). The hf_gray_16 global setting, as described in section
"HF_Gray_16" will also affect the type of data written to the output file."

I think I have to convert my file .pov to a .png
What do you think?
In the text box I put "+ua" and in the Pov code:
====================================
  background { White }
  camera {location <170, 11, -110>look_at  <180, -15, -16>}
  light_source { <170, -30, -100> color White}
======================================

Thank you very much,
Oleguer

  Just put "+fn" in addition to "+ua" to save as a png file (and you don't
need to specify the name of an output file; POV-Ray will automatically
save it to a png with a proper name).

-- 
plane{-x+y,-1pigment{bozo color_map{[0rgb x][1rgb x+y]}turbulence 1}}
sphere{0,2pigment{rgbt 1}interior{media{emission 1density{spherical

Yes, I didn't say it, I've did it. I've put in the text box "+ua +fs". Where
can I find the .png file? In the folder that the Pov-Ray save my files it
doesn't appear. Well, anyway, I'm goig to tray it again.

Best regards,
Oleguer

Sorry for being O.T. but I only have access to the web view.
It seems to me that this thread is a good example of the cooperation between
members of the Pov-Ray community. Gone is the dreaded RTFM, it has been
replaced with patience, good manners and knowledge transfer at a suitable
level.
