Thanks Steve,
yes i no saw before the "RGBA box" :) yes for export SINGLE IMAGE WORKs!
PS:only for test i try export .png image after render in "object mode" and the " RGBA box" for transparent pixels no work.. :'(
Steve:
Check out build 1124 with a few fixes and Layer support for Figure components.
thecolclough:
just downloaded 1124 and re-tried my multi-layer PNG test scene. it's now saving the RGBA frames correctly, but still generating Alpha-only files too. not a huge issue as i can bulk-delete them afterwards, but still a bug of sorts (i think?)
also, not sure if this got through last time, or if so what you thought about it:
--- Quote from: thecolclough on October 25, 2014, 09:08:56 am ---i've noticed that when you export a movie using Image + Alpha, any empty areas default to black in the RGB channels, instead of obeying the background colour set for the scene's environment. This could lead to unsightly dark edges around different render layers when they are composited in post-production, so could it be altered to fill empty areas with the user-defined background colour like it does when rendering without Alpha?

?
Steve:
thecolclough If you render a movie to RGBA .png files select only the image channel Anim8or makes full color RGB with the appropriate alpha channel. The background (where the alpha is 0) will be whatever color it is on the screen, which you can set to any color (or an image, etc) in the Scene->Properties dialog using the Environment button.
The black background and separate alpha images are created when you select Image+Alpha Channel which outputs both channels as you'd expect. The black background makes it possible to blend the images with another image an not result in a color fringe tinted the background color. This is not possible with the back ground color which can vary when you use an image or panorama. See the user manual for how this works:

That'll be what threw me - i assumed that if you selected Image only, it wouldn't include the alpha data. thanks for clarifying.

erm... i was about to protest that a black fringe is sometimes worse, but i suspect i've misinterpreted something here... *goes away to do a bit more reading about this compositing lark* :P
