2 questions (alpha and reload images)

Hi all

I'm giving my first steps in Fusion.

1-I'm trying to setup a simple image with alpha and something is going on....
What am I doing wrong please?

2- I have another file were I have loaded 5 render images, is there a fast way to reload all those images in case I re-render them ?

Thanks.

If alpha is in the image already, there is nothing to do.

If you are combining alpha and RGB then you have choices, here's two of them.

One is loader and loader to Channel Boolean node, put your RGB in the foreground input, your alpha in the BG, and set the copy as mode, and bg alpha to alpha
If your foreground is not pre-multiplied, then you will have to do that. This can be done by adding a matte node, and selection post multiple.

Another option is simply to use the matte node, and do a copy alpha with post multiple.

Your setup looks reversed. your adding mask input from RGB into the alpha. I personally don't like to mask the loader with another loader, it leaves you with limited control. copy/paste the code below into your flow.
