Hi Forum, just wondering if anybody has come up with a good solution yet for rendering shadows on a transparent background. The way I do it now is 1) render scene with white mesh in background to catch the shadows 2) render scene with white mesh hidden to get the alpha mask 3) use the 2nd image as the mask in photoshop and brush-in the shadows where I want them. Would be awesome, especially for video, to get the shadows rendered out with alpha channel.

you are probably speaking about shadow catching, it was asked several times... but not implemented yet.
personnaly for now, i'm doing same as yu, rendering shadows on white rough surface and using mask in picture editor, but it's limited especially for catching complex shadows.
