hi,

when I load my mxi in Nuke it seems the alpha channel doesn't load properly. what Nuke recognize as alpha channel is empty and there is among all my other passes a channel called ALPHA (capital letter) containing my rendered alpha.

is there a way to make Nuke properly recognize that this ALPHA should be in the alpha making it possible to use the premultiply option and so on...

thanks

In nuke, the MXI's alpha channel is loaded in its own layer called "ALPHA" as you said. You can add it to the rgb render channel (or whatever) using a "shuffle" node:
