I have done an effect in order to show dart vader open his light saber,the image of darth vader itself is transparent such that only his form and empty sword is seen,With Pi i made the Sword ,now i want to export the last image such that only the light saber and the darth are seen and i dont want any background
I tried all possible settins with Pi but always got a black background!!! Wat am i to do?
Does Pi not export or output transparency in PNG or PSD formats(i tried this As well!)
And also in the Psd Formats the Layers are not recognised
pI does export the transparency in those formats, but only the transparency of the particles themselves. It doesn't include any transparency information for the background video/images. So you'd have to export the particles alone, and lay them on top of vader in a paint, compositing or editing program.
If you want both the particle transparency and the BG transparency, the only way I can think to do this requires that you have a compositing program like After Effects, or an NLE like Vegas, premiere or final cut.
Render just your particles, bring the footage into your compositing app/NLE, composite you BG and particles, and render with Alpha.
