Transparent background animations
Hi,
I really just started today with Cheetah3D, and since I am the impatient guy :wink:, I already have a question:
How can I make a movie with transparent background?
The reason is, I will often include my images into Keynote presentations, which makes very nice to have a transparent background, so that the slide's background shows through the image.
This works fine with still images: in the camera render setting, I select the background color, and in the color picker, I drag the transparency slider all the way to the left (to zero). A simple copy and paste later, boum, I have a transparent-background image in my Keynote slide. Great.
Now, I couldn't make it work with movies. It seems I can set a transparent background color in the camera render settings. This gives the animation a "black" background from the render window. But then, I'm stuck:
- copy and paste only pastes a still image, not a movie.
- saving the movie (converting to quicktime movie, default parameters) yields a movie, but its background is not transparent.
Any idea? A quick search through the help and this forum didn't show up anything, but I would be glad to RTFM if I could be given a pointer.
A zillion thanks,
Jean-Denis
