Video grabber BG alpha mask

[hearan.yu]

I would like to render a character using video grabber,

 

but the "background alpha mask" function does not seem to work.

 

I think this function is a function that generates alpha layer of rendered objects by alpha processing the background part,

 

and I want to know what conditions are necessary to use it.

hearan.yu,

 

We will check what we can do here. Right now it seems that it looks more like a bug.

You also can try to apply following settings to get correct alpha on a screenshots:

1. Enable 16bit color format for the final image (Rendering -> Buffers -> Color 16F);

2. Disable Environment (Rendering -> Features -> Environment);

3. Modify Environment color: Rendering Settings (Alt + R) -> Common -> Background Color (set it to black and Alpha to 0 via sliders);

4. Disable DOF (if enabled): Rendering -> Camera Effects -> DOF;

5. Set Exposure mode to static: Rendering Settings (Alt + R) -> Camera Effects -> Exposure -> Mode: Static (adjust Exposure level to get more brighter picture).

Thanks!
