exported png image something wrong.
on Nov 8, 2009 at 9:12:40 am

Hi. I use particleIllusion 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.

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.
