Hey Kevin,
I just saved a png file(don’t know how..:)) and if I put this png file onto the timeline (composition window) then it has a perfect transparency background. The problem is that it’s only a frame, a picture and I have to still play around to figure out how to get the same but for an animation.
This is how I save it in C4D:
Render settings:
Format: quicktime PNG OPtions: millions of colors + (interlaced should be checked?)
alpha channel: checked
straight alpha: don’t know what is this
separate alpha: should this one be checked also?
Then I click on the make preview and I can choose that it should be a quicktime file. options: animation or PNG?
I think I will post this on the C4D forum also, since now I see if I could save it with a correct alpha channel it should be transparent automaticly in AE.
Thank you!
