  exported png image something wrong.

  Posted by Kazuhiro Eguchi on November 8, 2009 at 9:12 am

  Hi. I use particleIllusion 3.0.4.1 on Windows XP with NVIDIA GEFORCE 9500 GT. I think this is great tool.

  I want to export particles with BG image by .png format with alpha.

  But, I think exported image is not correct.

  

  My operations are below.

  – Read png image to BG.
  – Put Emiter on the stage.
  – Click Save output Icon.
  – Enter File name(aaa.png).
  – Check [save Alpha] and, click OK.
  – Open exported image by Photoshop cs2(or Flash 8, or google Picasa…), I think it looks something wrong(“half-translucent?”).

  

  Please tell me how to avoid this issue.

  Sorry my bad english.

  Regards.

  I’m not sure why you’re seeing your bg image at all — particleIllusion should only be creating the alpha channel using the particles (it does not use the bg image alpha).

  I suggest turning off the bg image then rendering, then composite with your bg image in another application.
