    Hi people! I am trying to pass an alpha information to a blur node and I can’t pass the information in any way, any advice?

    -I am getting the alpha information from a depth map node on an image and I want to pass it to the blur node to blur a specific part of the same image.

    -inside the fusion module.

    Hey Steve, I never used the depth map in fusion. What I can tell you, though, is that usually it works only if the depth map node is put in serial before the node that needs the alpha information. I still believe that is a bug, as logically does not make sense to me, but it is what it is. That said, given how complex the depth map is to run, I would suggest this approach: use it in the colour page and leave it to display the map. This way you can render out a black and white video of the mask, that you can later re-import as a matte for either fusion or the colour page.

    Hi Ricardo, thanks for the advice, it seems that it was indeed a bug, I went back to redo everything in a new composition and everything has worked fine, I could do what you said, it is also a good solution but in this particular case would not serve me … thanks for the info bro!
