Render with transparent background

[baoxiaohe_developer]

Hello,
I want to render a png image with totally transparent background like this:

When I put this image on my web site with black background, I got a white outline around the black cube:

This issue is casued by white background setting:

So I use an alpha=0 image as background like this:

But unfortunately this could not fix this issue, so is there any way to remove this OUTLINE?
Thanks.

Hi baoxiaohe_developer,

Currently that is not possible from within Vantage. You could try:

• the Defringe option(Layer menu > Matting > Defringe) in Photoshop with 1-3 px width. That should remove that outline but may eat out more pixels than needed, eg thin lines may get erased.
• the Remove White Mattes (Layer menu > Matting > Remove White Mattes)
• set a black color as background in Vantage and render that out. This should work in your case when using a black background but will produces a black outline if you decide to change your web site's background.

Please try it and report back if it works in your case.


Best regards,
Alexander

This didn't work for me. There is no "matting" option in the layers menu
