    Hello! I love 2.02 so I decided to try the beta today. I'm getting the hang of things, but I feel pretty stupid because I can't figure out why my renders have white backgrounds.

    While I'm working on the flame itself, the background is black. I've checked my presets and they indicate black. Once I render, the background turns white and my flame looks... less than nice.

    I'm sorry for posting such a newbie question, but I'm getting really frustrated with it. Any help is greatly appreciated.

      Are you rendering to PNG? And turned alpha channel on? This way your flames have a transparent background (not white). Try opening them in IrfanView.

      cheers, Peter.

      I'm having the same problem, except when I render as a .png, it is a flattened file with a black background. How to I turn alpha channels on? The earlier 2.0 version always rendered with a transparent background.

        The option is in Options -> Display -> PNG Transparency.

      That option is only in the beta version 2.05, which has to be "installed" each time you use it.
      Version 2.02 doesn't have the transparency option in any of the menus...unless I'm just not looking in the right place?

        errr.... what do you mean by 'has to be "installed" each time you use it' ??.... What are you talking about?...

        Apophysis 2.02 doesn't have such an option, it renders an alpha channel whenever you use PNG file.

      Only the 2.05 beta version renders an alpha channel and lets you set the png transparency in it's Options menu. Version 2.02 doesn't have such a setting in its Options menu. I never had this problem with the older 2.0 version. It would always render a png with a transparent background.

        As I said previously, 2.02 *does* render an alpha channel. It *does not* have an option for this, 'cause it renders it *always*, whenever you set an output to a PNG file.

      What I've been trying to explain is the same problem that Amalea had--rendering to a PNG file in version 2.02 doesn't produce a TRANSPARENT background like it should. There's no way to separate the image from the background, which is black in my case. It produces a flattened image--there is no extra alpha channel that serves as a clipping path to separate the two--just the usual Red, Green, Blue, and composite RGB channels.

        First: It *does* produce an alpha channel. Probably you are using some non-compatible viewer.
        Second: it doesn't matter ;) it's a so old version... why you are using it??....
