    Hi All,

    I seem to be missing someting, I don’t see an alpha channel when producing an effect using trail emmitters. Is this normal or could
    I have a problem with my program or is their something special I’m missing.

    Thanks

    You need to check the “Save Alpha” option in the output options dialog. This will only be enabled on Windows versions for TGA and PNG, and on Mac for the same and QuickTime movies if you have a compressor selected that supports alpha and set the number of colors to the highest.

    Thanks Alan,

    Iwas aware of your point. However, when I put a trail emmitter
    on the stage and select alt-A to view the alpha channel it
    isn’t viewable. Other emmitter do produce a alpha channel.
    Do Trail Emitter produce an alpha channel or could I have a problem with my program.

    Thanks

    You probably have “create non-intense alpha” (CNIA) turned on. Use “Alt-Shift-A” to toggle it. Easiest way to see this is to add an emitter (or two) that has some intense particles and some non-intense, view the alpha channel, then toggle CNIA.
